- Subject: math test failures in 2.2.92
Ulrich,
On debian ppc sid, I have built the current glibc 2.2.92
test release and am seeing the same sort of mail failures
Franz Sirl was seeing. I am wondering if these failures
are in anyway related to the compiler warnings associated
with the tests getting built...for example...
