Re: Compiler checks in AM_PROG_LIBTOOL

Thanks for all the replies to my question! I'm perfectly content with
the fix being in CVS -- it wasn't exactly an urgent problem.

However, the following leaves me a bit curious:

I don't know much about how libtool works, but if the compiler checks
are so unnecessary that I can just forcibly remove them like that, why
were they put in libtool to begin with? Is it some kind of historical
leftover? Not that it matters practically -- I'm just curious.
