Re: Current CVS - test suite failure

[Akim Demaille]

Thanks!  I'm applying the following patch.  I expect it to fix your
problems.

Index: ChangeLog
from  Akim Demaille  <address@hidden>
        * acgeneral.m4 (_AC_RUN_IFELSE): Remove conftest.o when cleaning
        up.
        * acfunctions.m4 (AC_FUNC_WAIT3): Use `break' to silent some
        warnings from compilers.
        * aclang.m4 (_AC_LANG_COMPILER_GNU): Log the version information
        for all the compilers, not only GNU.  Hence move from here...
        (AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): to here.
