C:\ghc\ghc-6.11.20090118\gcc-lib\ld.exe: cannot find -lHSffi_p

[Claus Reinke]

Is profiling for code involving ffi supposed to work?
The error above results from trying to build (windows xp,
mingw/cygwin) with

ghc --make -O2 SimpleGo.hs -prof -auto-all -caf-all

No profiling version of ffi seems to exist:

$ ls /cygdrive/c/ghc/ghc-6.11.20090118/*ffi*
/cygdrive/c/ghc/ghc-6.11.20090118/HSffi.o  
/cygdrive/c/ghc/ghc-6.11.20090118/libHSffi.a

Do I need to change any GHC build settings to get that,
or is it just not supported?

Btw, is there a non-hackish way of seeing which
packages have profiling support?
