Only because the default CFLAGS has -g in it; if you do need to override it,
you must specifiy -g yourself.

I'd recommend using CFLAGS='-g3 -O0' myself. It's worth having the debug
info level turned right up.
FTR, I configure like this:
$ ./configure -C --disable-shared --host=i686-pc-mingw32 \
--build=i686-pc-cygwin CC="gcc-3 -mno-cygwin" CXX="g++-3 -mno-cygwin"
CC_FOR_TARGET="gcc-3 -mno-cygwin" CC_FOR_BUILD="gcc-3 -mno-cygwin" \
CXX_FOR_TARGET="g++-3 -mno-cygwin" --disable-shared
I need to go back and check whether all of those are strictly necessary, but
I did find gcc-4 kept creeping back into my builds without them. IIRC, the
gpg-error lib needs to run a generator exe during the build, and I figured we
should probably build that as a mingw exe too, hence the _FOR_BUILD settings.
I'm not sure if the FOR_TARGET settings are needed still, I wasn't systematic
in testing this, just kept adding settings until gcc-4 stopped showing up in
the build logs.
