Subject: compiling musl on x86_64 linux with ppc

Hello,

I am trying to compile musl 1.1.4 on x86_64 with ppc (latest from cvs).

Unfortunately the compilation breaks with

-----------
 ...
pcc -std=c99 -nostdinc -ffreestanding -fexcess-precision=standard -frounding-math -D_XOPEN_SOURCE=700 -I./arch/x86_64 -I./src/internal -I./include  -Os -pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables -Wa,--noexecstack -Werror=implicit-function-declaration -Werror=implicit-int -Werror=pointer-sign -Werror=pointer-arith -fno-stack-protector  -c -o src/aio/aio_readwrite.o src/aio/aio_readwrite.c

-----------

Is there any way around this, short of adding the register assignment
functionality to the compiler?

Regards,
Rune
