This sounds like #58579.
I have a minimal testcase for it, no fix yet.
On the other side, why aren't you using RPM_OPT_FLAGS? This bug never happens
with -mcpu=i686...

Comment 3 Tim Waugh 2002-01-22 07:01:51 EST

Just because CFLAGS="$RPM_OPT_FLAGS" breaks the package because it puts 
includes in CFLAGS in the Makefile.  I'll patch the Makefile so that using 
RPM_OPT_FLAGS works.  Thanks.

Comment 4 Jakub Jelinek 2002-02-01 11:19:49 EST

Fixed in gcc-3.1-0.19.
