After downloading the pgcc v2.95.1 SRPMS from Erhan Bilgili's site
(ftp://ftp.deu.edu.tr/pub/linux/PentiumGCC/SRPM/pgcc-2.95.1-1.src.rpm),
I attempted to build it on my RedHat 6.0 (with v2.2.11 kernel) system.

I initially attempted to build the SRPM with the switches "-mcpu=i585 -O3"
(this is the value of the RPM_OPT_FLAGS used in the spec file).  Doing so
caused an internal compiler error (ICE) when the 2nd stage of the build
process began.  I backed it down to "-mcpu=i585 -O2" and the compiler
built successfully.

After installing the newly-built pgcc binaries, I attempted to rebuild the
glibc libraries (in the form of glibc-2.1.1-7.src.rpm).  Again I found
that "-mcpu=i585 -O3" whould cause an ICE, where "-mcpu=i585 -O2" would
not.

Has anyone else seen this problem?

One thing I should note: I am using binutils v2.9.1.0.23, as provided by
RH 6.0, where v2.9.1.0.25 is recommended.  Could this be a factor in my
inability to go above -O2 optimization?  Where can a find a (S)RPM of
binutils v2.9.1.0.25?

Thank you.
