Follow-up Comment #4, sr #110451 (project autoconf): > AC_PROG_CC(_C99) intentionally doesn't use -xc99 with Sun's compilers. ... see the thread starting at: https://lists.gnu.org/archive/html/autoconf/2010-12/msg00059.html
Indeed, this option, together with the per-program flags __xpg4 and __xpg6 makes it impossible to build reliably working libraries. So, I withdraw this suggestion. > The test for C99 compliance was made pickier in Autoconf 2.70, and -D_STDC_C99, which it does use, is no longer enough for Sun's compiler to pass the test. I have now documented the use of -D_STDC_C99 in https://gitlab.com/ghwiki/gnow-how/-/wikis/Platforms/Configuration; nevertheless it was good that Autoconf 2.69 added -D_STDC_C99 automatically. Support for part of C99 is better than support for none of C99. Therefore a less picky test is better than a pickier one. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/support/?110451> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
