* unsetenv: work around Haiku issuesEric Blake2011-02-051-4/+14
| | | | | | | | | | | | | | | | | | | On Haiku alpha 2, test-unsetenv.c passed in isolation with just system headers, but failed when libgnu and replacement headers were in use. Why? Because putenv("a") fails to remove "a=..." from the environment, but the gnulib rpl_putenv works by assigning to environ. Apparently, Haiku is doing some funky caching issues, and correctly removes all vestiges of environment duplicates when Haiku is in charge, but not after assigning to environ forces Haiku to rebuild its cache. The m4 change is sufficient to detect Haiku's oddities, and the existing replacement then passes just fine. * m4/setenv.m4 (gl_FUNC_UNSETENV): Also detect Haiku issue. * doc/posix-functions/unsetenv.texi (unsetenv): Document it.

* many *.m4 files: improve m4 quotingJim Meyering2009-01-141-7/+7
| | | | | | | | | | | | | | | | 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.
