Jim Meyering 42d1eda5 2009-01-13T08:48:48 many *.m4 files: improve m4 quoting 99% of this change was performed by running the following commands: git ls-files | grep '\.m4$' | xargs perl -pi \ -e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \ -e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g' perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4 The remainder were to add Copyright dates, increment serial numbers, undo some changes in comments, exclude m4/intl.m4, and add quotes around the "1" in ",1" where the unusual spacing prohibited the above regexps from doing the job.

Bruno Haible 67461c3a 2008-12-06T15:01:09 Treat SIGBUS like SIFSEGV on platforms that need it.
Eric Blake 91a109c0 2008-09-23T08:56:10 c-stack: avoid compiler optimizations when provoking overflow * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Make recursion harder to optimize, to ensure a stack overflow occurs. * tests/test-c-stack.c (recurse): Likewise. Borrowed from libsigsegv. Signed-off-by: Eric Blake <ebb9@byu.net>
Eric Blake ad736828 2008-09-23T08:47:26 c-stack: work around Irix sigaltstack bug * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Check whether sigaltstack uses wrong end of stack_t (copied in part from libsigsegv). * lib/c-stack.c (c_stack_action) [!HAVE_LIBSIGSEGV]: Work around Irix bug, without requiring an over-allocation. * doc/posix-functions/sigaltstack.texi (sigaltstack): Document the bug.

Reported by Elbert Pol. Signed-off-by: Eric Blake <ebb9@byu.net>

Paul Eggert f49d92a1 2004-03-07T23:51:09 Fix c-stack.c portability bug on IRIX 5.3.
Paul Eggert 60121218 2003-08-17T00:09:27 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Limit stack size to 1MB, so as not to render systems with no stack size limit (e.g., linux-2.2.x) unusable. Suggestion and code from Bruno Haible. Include <unistd.h>. On some systems, it is required for the definition of _SC_PAGESIZE.
Bruno Haible e059c235 2002-12-31T13:43:06 An independent .m4 file for each module.
