As previously mentioned I wiped and installed a clean debian. I did a absolute minimum default install no desktop etc compiled the latest stable musl, m4, gmp, mpfr, mpc, and downloaded gcc 4.7.3 with gregorr/musl-cross patch to match.  I ran the build based on the commands i found in his script and even tried passing --disable-werror to no avail (it helped on binutils so i figured it was worth a shot).  Libgcc still errors out when using --target.

Its having a problem finding/using libmpc.so.3 but the paths appear to point to the directory which it is located. to be sure i even specified using the --with-mpc flag.

If you could please take a moment to help me with this i would appreciate it. Libmpc is in /root/cross/i686-linux-musl/lib and i have copied my config.log from the libgcc directory below

I've been using linux to some degree or form since the 486 was hot stuff so it also seems like about time i learn what makes it tick. man i remember getting a cyrix processor to replace my pentium thinking the increase in mhz would be better but boy was i wrong!  k, enough of that. moving on to newer things :)

Correction, pentium., we just purchased a pentium computer so i took the 486 and installed a lilo booting redhat linux version 5.2? 6.2? i purchased from a local software store.  good memories.
