This also fixed a bug in error context for additional token list parameters, introduced by their reorganization. 2004-07-21 Olaf Weber * etrip/etripin.log: Update from Preter Breitenlohner. * etrip/etrip.tex: Update from Peter Breitenlohner. * etrip/etrip.fot: Update from Peter Breitenlohner. 2004-07-19 Peter Breitenlohner * etex.ch, tex.ch[01]: Reorganize handling of additional token list and integer parameters and e-TeX's additional penalties in order to reduce interference between eTeX, pdfTeX, and web2c change files. * etex.ch: Add a note that this file not only defines etex.web in terms of changes to be applies to tex.web, but in addition is used to define pdfetex.web. * tex.ech: Add a note that this file is used to construct the web2c change files for both e-TeX and pdfeTeX. 2004-07-17 Peter Breitenlohner * etex.ch: Towards etex-2.2: Adapt to TeX 3.141592; this is still somewhat preliminary; do_glue still needs to be adapted to the new glue rounding algorithm of TeX 3.141592. Incorporate bug fixes from etex.fix. * etex.ch0, etrip/etrip.{fot,tex}, etrip/etripin.log: Adapted to TeX 3.141592. * tex.ch1, tex.ech: Change the xmalloc_array calls to the `new' interface (from 2001-11-10). * etex.ch0, etex.ch1, etex.fix, tex.ch2: Removed. * etex.mk: Rewrite build rules for etex.{web,ch}, add etexdir/etex.mk and remove etex.{ch0,ch1,fix}, tex.ch2. * etex.version: add newline. * etrip/etrip.log, etrip.diffs: changed due to bug fix. 2004-07-14 Olaf Weber * etex.fix: Add fix for typo on line 2737 of etex.ch. From Peter Breitenlohner. * etexextra.h: Add BUG_ADDRESS. 2004-07-04 Olaf Weber * etex.mk: Move the creation of the format-related links to format-related install rules; this seems to be a better place for them, as the links are pointless without the corresponding formats. Make the install-*-pool rules depend on the pool file in question. 2004-07-03 Olaf Weber * etex.mk: Set up the make rules so that if etex isn't built (by default) we do not forward from the general to the etex-specific rules. But the etex-specific rules can be used. * etex.mk: Use $(TANGLE), $(TIE) instead ./tangle, ./tie to support cross-compiling. 2004-05-10 Olaf Weber * etex.mk (install-etex-programs): Typo resulted in no etex binary being installed. 2004-05-08 Olaf Weber * etex.mk (install-etex-programs): This rule didn't have a command attached, so etex didn't get installed. (install-etex-links): Dont install einitex, evirtex links. * etex.mk: Formats are now parked in a subdirectory of $(web2cdir). * etex.mk: Change the .efmt extension to .fmt. One consequence is that we don't want to build tex.fmt, where we could safely build tex.efmt. * etexextra.h: .efmt -> .fmt. * tex.ech: .efmt -> .fmt. 2004-01-27 Olaf Weber * etex.fix: The assignment to cur_val instead of cur_val_level would result in \lastnodetype getting confused about what type of value it was supposed to be. Reported by Hartmut Henkel , fix found by Fabrice Popineau . 2003-02-19 Olaf Weber * etex.mk: Installation of formats is no longer done via install-data in this file, but just from the install-data -> install-dumps -> install-fmts in the main Makefile. That way we can prevent automatic installation with a single change in that Makefile. (etex.p): Depend on tangle. (triptrap): Depend on etrip. (install-etex-data): Double-colon rule. (install-data): Combine with install-etex-data. 2003-02-17 Olaf Weber * etex.ch1: Reduce to banner changes. * etex.ch0: Slightly extend the reverted bits here, so they can be cleared out of etex.ch1 and are now all in one file. 2003-02-16 Olaf Weber * etex.ch1: Correct the banners, and revert a final few bits of TeX that use a variable that doesn't exist in e-TeX. * etex.ch0: TeX 3.141592 and e-TeX 2.1 require reconciliation. Revert some of TeX's code to 3.14159 to get e-TeX 2.1 to tangle. * etexextra.h: Update banner for 3.141592-2.1. * etex.mk (etex.web): Add etex.ch0 and etex.ch1 to build rules. 2003-02-15 Olaf Weber * etex.mk: From klibtool to libtool. Based on patches from Albert Chin-A-Young . * etex.mk: Changes to make e-TeX, in extended mode, the engine under LaTeX2e. 2003-02-07 Olaf Weber * etex.mk: Reorganized to match the new Makefile.in. 2003-01-15 Olaf Weber * etex.mk (etestenv): Add LC_ALL=C to the etrip environment. 2002-10-11 Olaf Weber * tex.ch1: Settle on a text for the not-TeX banner. 2002-06-02 Olaf Weber * tex.ch0, tex.ch1: Changes to account for the banner changing when certain options are specified that make the program not-strictly TeX. * tex.ch2: Commented-out changes deleted. These changes became active in tex.ch1. Mon Feb 01 18:35:30 1999 Peter Breitenlohner * Version 2.1 for Web2c Version 7.2 Thu Feb 19 18:03:12 1998 Peter Breitenlohner * Version 2.0 for Web2c Version 7.2 Sat Aug 23 14:14:12 1997 Peter Breitenlohner * Integrated e-TeX Version 1.1 into Web2c Version 7.0 (by Karl Berry, as of Feb 7 1997. All e-TeX (and e-TRIP) source files as well as a Makefile fragment are in a separate directory: web2c/etexdir. This will certainly make it easier to switch to e-TeX Version 2.
