Yeah, but ...

*Yes*.  This is exactly the problem, really.  One could reasonably
accuse the autoconf developers of FSF imperialism, because they have
seen to it that autoconf-based configure scripts will choose non-optimal
CFLAGS for non-gcc compilers.  These same geeks would be screaming for
Microsoft's blood if Microsoft tried comparable tactics, so I don't have
a whole lot of sympathy.

(Side note: I've been overriding this particular autoconf-ism in
libjpeg's configure script since about 1995, so it's not like my
antipathy to it is a new subject.)

I hear where he's coming from, believe me.  But RPM builds generally strip
the binaries anyway, so autoconf isn't really accomplishing anything
with this that I can see.  The mass market won't be providing stack
traces with their bug reports, whether the binary has symbols or not.
