Hi all,
I have a fix for this. It seems that just recently (since
bd8f7fc56b84369f4e820263c0bcdc85760de6d4) ghc has started calling
gcc with extra comand line parameters:
-x assembler
>From the gcc man page
-x language
Specify explicitly the language for the following input files
(rather than letting the compiler choose a default based on
the file name suffix). This option applies to all following
input files until the next -x option. Possible values for
language are:
c c-header cpp-output
c++ c++-header c++-cpp-output
objective-c objective-c-header objective-c-cpp-output
objective-c++ objective-c++-header objective-c++-cpp-output
assembler assembler-with-cpp
ada
f77 f77-cpp-input f95 f95-cpp-input
go
java
The attached patch replaces '-x assembler' with '-x assembler-with-cpp'
and fixes the problem for me on powerpc.

Subject: [PATCH] Call gcc with '-x assembler-with-cpp' instead of '-x
assembler'.
One x86 and powerpc, the second form above was ignoring all the CPP
lines and hence trying to compile x86 asm on powerpc and powerpc asm
on x86.
