Comment (by igloo):
I think that something like this might be the way to go:

but (in the HEAD) having the align on amd64/Linux gives me:

[GHC] #1605: hppa port -- gmp handed misaligned memory
#1605: hppa port -- gmp handed misaligned memory -+-- Reporter: guest | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System |Version: 6.6.1 Severity: normal | Keywords: GMP Difficulty: Easy (1 hr) | Os: HPUX Testcase: | Architecture: hppa -+-- GMP compiled for hppa 2.0n uses 8 byte data by default. hppa *requires* that 8 byte data be aligned on an 8 byte boundary. However GHC only aligns allocated memory to a 4 byte boundary. This causes GHC to crash. Currently the workaround is to recompile GMP to use 32 bit data, but this is probably a performance hit.
