AC_PREREQ(2.4)dnl Required Autoconf version.
|

dnl Do not use autoconf 2.12; it produces a configure script which produces
|
|
dnl a "internal 2K buffer" error on HPUX when run with /bin/sh.
|
|
dnl autoconf 2.10 seems like a good choice.
|
|
dnl
|
|
dnl It is possible that we should just change the above required version
|
|
dnl to 2.10; it seems like everyone is using 2.10 anyway, and there is
|
|
dnl at least some sentiment that we should be using a version which has
|
|
dnl --bindir (and correspondingly, using @bindir@ and friends in our
|
|
dnl Makefile.in files. Rumor has it that autoconf 2.7
|
|
dnl introduced --bindir but the point is that 2.10 has it.

dnl The CVS coding standard (as specified in HACKING) is that if it exists

dnl AC_FUNC_VFORK is rather baroque. It seems to be rather more picky
|
|
dnl than, say, the Single Unix Specification (version 2), which simplifies
|
|
dnl a lot of cases by saying that the child process can't set any variables
|
|
dnl (thus avoiding problems with register allocation) or call any functions
|
|
dnl (thus avoiding problems with whether file descriptors are shared).
|
|
dnl It would be nice if we could just write to the Single Unix Specification.
|
|
dnl I think the only way to do redirection this way is by doing it in the
|
|
dnl parent, and then undoing it afterwards (analogous to windows-NT/run.c).
|
|
dnl That would appear to have a race condition if the user hits ^C (or
|
|
dnl some other signal) at the wrong time, as main_cleanup will try to use
|
|
dnl stdout/stderr. So maybe we are stuck with AC_FUNC_VFORK.

dnl We always use CVS's regular expression matcher.
|
|
dnl This is because:
|
|
dnl (1) If memory serves, the syntax of the regular expressions
|
|
dnl handled by re_exec is not consistent from system to system, which
|
|
dnl is a Bad Thing because CVS passes this syntax out to the user.
|
|
dnl We might have better luck with the POSIX interface, if we really
|
|
dnl want to look for a system-supplied matcher.
|
|
dnl (2) It is necessary to make _sure_ that we get a regex.h and regex.c
|
|
dnl that match each other. In particular, rx and the CVS/emacs
|
|
dnl regex.c have a different "struct re_pattern_buffer" and so using
|
|
dnl the system regex.h and our regex.c, or vice versa, will tend to
|
|
dnl cause a core dump.
|
|
dnl (3) Just as a random data point, CVS uses re_exec (a BSD interface);
|
|
dnl libdiff uses re_compile_pattern (a GNU interface, I think). Diff
|
|
dnl should probably be fixed to have the caller (CVS) supply the regexp
|
|
dnl matching.
