Presumably, the IPA information is stored in the directory of the
test. Why not create a shell script that wraps the compiler executable
that removes these temporary files? Then, rebuild with:
./configure CC=<path to IPA-compiler wrapper> ...
I guess because the only place I see it useful is in the configure
when testing libraries. It would also exhibit a problem to end-users
that would require them to read a readme file and follow the
instructions :)! Anyways, I put "rm -f *conftest*" at the end of my
autoconf macro definition and it seems to work fine on linux. I guess
I'll deal with other platforms as they exhibit problems. I was just
wondering if there was a more "portable" way of making sure that all
test files were removed.
