[more of the same elided]
The reason is that the split markers (__STG_SPLIT_MARKER in
includes/Stg.h) that the ghc compiler inserts into
C code are emitted differently into assembler with gcc-4.1 and gcc-4.2.
The latter seems to kind of delay them, so part of actual assembler code
is now before the first emitted split marker, which then is erroneously
taken as prologue material and copied into every split assembler source
resulting in lots of duplicate definitions.
As a temporary workaround, a build with --with-gcc=gcc-4.1 succeeds.
Cheers, Roderich
