Tim,

It is reasonable if you set the LIB and INCLUDE environment variables to
point to the MSYS /usr/local/lib and /usr/local/include directories. Of
course you'll have to build the c library from source in MSYS/MinGW for this
to work. You'll also have to manually copy the dll files to a location in
the PATH.

set LIB=%LIB%;C:\MSYS\1.0\local\lib
set INCLUDE=%INCLUDE%;C:\msys\1.0\local\include

You can this as a one time change in the Systems control panel.

If you install the C library from a binary distribution (usually installed
in some arbitrary location on the pc) then the easiest way is to edit the
cabal file.

Cheers,

Olivier.
