| I don't think Python 2.7 should upgrade to a newer autoconf version at this point. For 3.2, we could try it out. |

| You don't need to add source in case of AC_COMPILE_IFELSE([AC_LANG_SOURCE([[]])] .. when the the test is ..main() { return 0 ;} ... , posted long time ago as part of ( minimal cross-compilation support for configure ). Also thanks for fixing extra comma in after replacement of AC_TRY_COMPILE . This part is save to be added to 2.7 build. |

| r81004: Remove extra closing bracket and comma introduced in r80969. (This was causing misdetection of the OS X 10.5 SDK on Linux and OS X, and a test_platform failure on OS X.) |

| I don't have access to source so my comment will be based only on diffs from above mentioned revisions. r80969: - AC_LANG_PROGRAM ... with main function in body . It is legal as I don't know C compiler that fail to compile code like ...int main() { int main() {...} ...} but is better to left body empty. Counted three times. All those cases tests for compiler flags and I think that AC_LANG_SOURCE is enough. - body include #include "confdefs.h" - may be buggy (before) and now AC_LANG_PROGRAM will add all defines. Counted any times. I think that is save to remove #include "confdefs.h" from all those test cases. |

| Roumen: good catch! Indeed, nested functions aren't legal in standard C, and the test for -fno-strict-aliasing now fails on my OS X 10.6.3 machine, where it used to pass: checking whether gcc accepts -fno-strict-aliasing... no config.log contains: configure:5400: checking whether gcc accepts -fno-strict-aliasing configure:5418: gcc -fno-strict-aliasing -c -g -O2 conftest.c >&5 conftest.c: In function 'main': conftest.c:27: error: nested functions are disabled, use -fnested-functions to re-enable configure:5418: $? = 1 configure: failed program was: ... Fixed these cases above and removed the extra '#include "confdefs.h"' lines (which seem harmless, but unnecessary) in r81077 (trunk). |

| BTW, it looks as though the nested functions were introduced in r76030; nothing to do with Matthias's autoconf 2.65 update. |

| Just double checked that r80969 didn't introduce any other non-whitespace changes: apart from the now-fixed OS X 10.5 SDK issue), the only other non-whitespace change was: @@ -7018,7 +7023,7 @@ int main () { -long double x; x = (long double)0.; +long double x; x = (long double)0; ; return 0; } which looks harmless to me. |

| Closing. Roumen, please open a new issue for any other configure issues that aren't related to this autoconf update. |
