"Prologue junk?" error when building GHC

As far as I can tell this is a bug in the Evil Mangler.

This is on Windows, using MSYS to build. The relevant make output, compiling the HEAD:

make -C rts
make[1]: Entering directory `/D/Programming/src/ghc-HEAD/rts'
d:/Programming/src/ghc-HEAD/ghc/stage1-inplace/ghc  -fvia-C -static  -I../gmp/gmpbuild
-I../libffi/build/include -I. -dcmm-lint     -c Apply.cmm -o Apply.o
Prologue junk?: .globl _stg_ap_0_fast
_stg_ap_0_fast:
/APP
 # 9 "C:\Temp\/ghc3572_0/ghc3572_0.hc" 1

make[1]: *** [Apply.o] Error 9
make[1]: Leaving directory `/D/Programming/src/ghc-HEAD/rts'
make: *** [stage1] Error 2

This happens also when building 6.10.1, so it's not a HEAD problem. I didn't try other GHC versions.

gcc --version:

gcc.exe (GCC) 4.3.0 20080305 (alpha-testing) mingw-20080502

Attached is a .raw_s obtained by running the ghc command with -keep-raw-s-file.
