Subject: make check fails with -march=i686 on gcc 2.96 (PR#2296)
Message-ID: <200211151921.UAA15447@pubhealth.ku.dk>

The top-level 'make check' fails on Red Hat Linux 7.3 (fully patched 
as of Nov. 15, 2002) when CFLAGS includes "-march=i686". In 
particular, the following targets fail:

* test-Reg
* test-Examples
* test-Ts

The workaround is not to use "-march=i686". Specific stuff below, and
I'd be happy to provide any files or fragments thereof that'd help.

The failure does not occur

a) when the configure script is allowed to generate the optimization
   flags all on its own:

b) using Red Hat 8.0 with gcc 3.2 and glibc 2.2.93 (even with 
   -march=i686 specified)
