Configuring for debug info

[Niels Möller]

What's the recommended way of configuring gmp to get debug information
in the files? I'm using a plain gcc-3.2.2, running on an x86 linux
box. If I configure with

  ./configure --enable-maintainer-mode --enable-assert

I get CFLAGS set to -O2 -fomit-frame-pointer -mcpu=athlon
-march=athlon, no -g in sight.

I've also tried setting CFLAGS=-g on the ./configure command line, but
that replaces the automatic flags completely. Explicitly writing

  ./configure --enable-maintainer-mode --enable-assert \
     CFLAGS="-g -O2 -fomit-frame-pointer -mcpu=athlon -march=athlon"

seems to work but is kind of clumsy, as gmp knows the cpu flags much
better than I do.
