* fortran: define $GFC to "yes" if $FC is a GNU compilerStefano Lattarini2011-10-213-0/+17
| | | | | | | | | * lib/autoconf/fortran.m4 (AC_PROG_FC): Define `$GFC' to "yes" if the detected fortran compiler is a GNU compiler, define it to the empty string otherwise. This is mostly for consistency for what is done for the C, C++ and Fortran 77 compilers. * doc/automake.texi: Update.
* admin: mention recent copyright assignmentsEric Blake2011-10-132-0/+7

| | | | | | | * doc/autoconf.texi (Signal handling): Rename ... (Signal Handling): ... to this, for consistency with other node names. Fix some typos and grammaros. Add more URL references in comments.
* docs: korn shells can have $? > 256 for signal-terminated childrenStefano Lattarini2011-10-062-0/+72
| | | | | | | | | | | | Some Korn shells, when a child process dies due to signal number n, can leave in $? an exit status of 256+n, instead of the more common 128+n. See also Austin Group issue 0000051: <http://www.austingroupbugs.net/view.php?id=51> * doc/autoconf.texi (Signal handling): Document the described Korn Shell behaviour, and some of its possible shortcomings. Suggestion by Eric Blake.
* docs: relax documentation license by dropping cover textEric Blake2011-09-263-9/+14
| | | | | | | | | | | | See https://lists.gnu.org/archive/html/bug-diffutils/2011-08/msg00022.html for precedence in diffutils. The autoconf manual, as of this commit, was still barely below 400 pages. * doc/autoconf.texi (copying): Drop front- and back-cover texts. * NEWS: Document this. Reported by Brian Gough. Signed-off-by: Eric Blake <eblake@redhat.com>
* docs: signal-related bugs and incompatibilities for the shellsStefano Lattarini2011-09-202-0/+104
| | | | | | | | | | | * doc/autoconf.texi (Signal handling): New paragraph. (@menu at "Portable Shell", @detailmenu): Update. Motivated by recent discussion on the bug-autoconf list, as well as work in the automake testsuite: <https://lists.gnu.org/archive/html/bug-autoconf/2011-09/msg00003.html> <https://lists.gnu.org/archive/html/bug-autoconf/2011-09/msg00004.html> <http://lists.gnu.org/archive/html/automake-patches/2011-09/msg00066.html>

* docs: more details about make VPATH rewriting woesStefano Lattarini2011-09-162-8/+41
| | | | | | | | | * doc/autoconf.texi (Automatic Rule Rewriting): Solaris make VPATH rewriting applies to any whitespace-separated word in a rule, so it might apply also to shell variables, functions and keywords (and automake has already tripped on this once); document this, with an example. Since we are at it, do some minor reformatting of existing text.
* docs: document Solaris 10 /bin/ksh and XPG4 sh 'unset' bugStefano Lattarini2011-09-132-1/+9
| | | | | | * doc/autoconf.texi (Limitations of Builtins): Solaris 10 ksh and XPG4 sh also fails upon `unset' of a variable that is not set.
* docs: improve the prose describing _AC_CHECK_TYPE_NEW_BODYJim Meyering2011-09-012-7/+14
| | | | * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW_BODY): Improve prose.
* AC_C_CONST: don't reject gcc -Werror -WallPaul Eggert2011-08-312-8/+23
| | | | | | | | | | | | | * lib/autoconf/c.m4 (AC_C_CONST): Don't reject gcc when it is used with -Werror -Wall during configuring. It's unwise to use GCC that way, but apparently enough people do it nowadays that it's an issue. These days nobody uses the old compilers that the old tests reject, so we can't test this fix against them, but it's more important to work with modern GCC (even when misused) than to work with no-longer-used compilers. Problem reported by Shevek in <http://lists.gnu.org/archive/html/bug-autoconf/2008-11/msg00007.html> and raised again by Dan Kegel in <http://lists.gnu.org/archive/html/bug-autoconf/2011-08/msg00020.html>.
* docs: other issues with parallel BSD makeStefano Lattarini2011-08-182-46/+107
| | | | | | | | | | | Motivated by automake bug#9245: <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9245> and FreeBSD PR bin/159730: <http://www.freebsd.org/cgi/query-pr.cgi?pr=159730> * doc/autoconf.texi (Parallel Make): Document other BSD make incompatibilities. Reorganize the existing related documentation accordingly.

* docs: another Solaris sh bug with redirected `:'Stefano Lattarini2011-08-042-2/+13
| | | | | | * doc/autoconf.texi (File Descriptors): Solaris 10 /bin/sh "optimizes" away redirected `:' commands in a shell function after the first call.

| | | | | This is imported from gnulib. gnulib also has an HP-UX 11.11 fix, but let's see if we can do that another way, as it's pretty heaviweight.
