[xemacs-hg @ 2003-01-12 11:03:13 by michaels] 2003-01-12 Mike Sperber <mike@xemacs.org> * configure.in: Check for strupr and strlwr. 2002-12-16 Ben Wing <ben@xemacs.org> * INSTALL (Rationale): * configure.in (XE_COMPUTE_RUNPATH): * configure.usage (Usage): * configure.usage (--xemacs-compiler): * configure.usage (--srcdir): * configure.usage (--with-prefix): * configure.usage (--bindir): New. * configure.usage (--datadir): New. * configure.usage (--statedir): New. * configure.usage (--libdir): New. * configure.usage (--infodir): New. * configure.usage (--mandir): New. * configure.usage (--lispdir): New. * configure.usage (--sitelispdir): New. * configure.usage (--etcdir): New. * configure.usage (--lockdir): New. * configure.usage (--archlibdir): New. * configure.usage (--docdir): New. * configure.usage (--moduledir): New. * configure.usage (--with-site-lisp): New. * configure.usage (--with-site-modules): New. * configure.usage (--package-path): New. * configure.usage (--infopath): New. * configure.usage (--with-xmu): * configure.usage (--with-tty): * configure.usage (--with-gif): * configure.usage (--native-sound-lib): * configure.usage (--with-xim): New. * configure.usage (--with-clash-detection): New. * configure.usage (--with-database): * configure.usage (--mail-locking): * configure.usage (--with-ipv6-cname): Removed. * configure.usage (--error-checking): Redo usage message more logically, fix some problems. In configure, when outputting the compilation options, put in a big ugly warning about using union-type, since it's been known to trigger so many compiler bugs, invariably leading to weird crashes.
