Hello!

First at all: I'm NOT a member of the pgcc mailling list. So please feel
free to mail me directly....

I tried to compile glibc with pgcc 2.95.3.
My base system is SuSe 6.2 with Kernel 2.2.13 installed on a PII-300.
I extracted the pgcc binary tar-files from www.goof.com/pcg to the
standard installationpath /usr/local/pgcc.
I set the CC-Environment to /usr/local/pgcc/bin/gcc and
CFLAGS Environment to -mpentiumpro -march=pentiumpro -O3.
After that i extracted the glibc sources (with crypto and linuxthread) to
a sourcedirectory. I created the directory /usr/local/pglibc and run
srcdir/configure --enable-add-ons --prefix=/usr/local/pglibc in that
directory. After that I run make. All works fine.
But there seems some problems with the fpu-code, because when I run make
check I got the following warnings:
------------------- snip --------------------------
__erfl not implemented
__erfcl not implemented
__ieee754_lgammal_r not implemented

And finally the following error(s):
