However, I would still be interested to know if there's a way of passingspecific options to the C or C++ compiler when `configure' runs its tests without having to go deeply into the guts of Autoconf. I have looked into it a bit, but it seems like a major undertaking to really understand how to use it at that level.
You can change the relevant flags before the invocation of the compiler and restore them afterwards. The typical idiom is this:
saved_CFLAGS=$CFLAGS CFLAGS="$CFLAGS -my-new-flag" AC_TRY_LINK(...)# now you know whether -my-new-flag works and you can take the appropriate action
CFLAGS=$saved_CFLAGS Cheers, -- Benoit Sigoure aka Tsuna EPITA Research and Development Laboratory
