I estimate it would be 300+ hours work to make gcc 2.8.1 successfully
build glibc 2.1 on ppc at -O2.  I don't have this time available for
free.

When I tried it, it stopped at:

/tmp/cc6NoN6W.s: Assembler messages:
/tmp/cc6NoN6W.s:953: Error: Subtraction of two symbols in different sections ".L856" {.text section} - ".L855" {.rodata section} at file address 3398.
/tmp/cc6NoN6W.s:954: Error: Subtraction of two symbols in different sections ".L856" {.text section} - ".L855" {.rodata section} at file address 3402.

compiling posix/glob.o [note! not even glob.so!]

To me, this indicates that _no-one_ is using gcc on powerpc, not even
for compiling normal applications, let alone for huge complex shared
libraries with -fpic, and it would be lots and lots of work to make it
reliable.


For the GCC bugs list, this is with:
