caching

[Stefan Seefeld]

hi there,

I'm in the situation where I run the macro

AC_PATH_PROG with a program 'foo-config' and a given path,
and then, if that failes, I call it again (after some other
processing) with a different path.

autoconf will silently skip the second test as it has the result
of the first still in the cache. Is there a way to erase the cached
value ? or do I need to avoid reusing the same variable ?

Thanks,
                Stefan
