Understanding the undefine flags passed to gcc when linking

Hi, When I run 'ghc -v ...', the linking is done via gcc->ld with a large list of -u flags passed in. I'm hoping to find a way to link my object files without those flags, but first I need to understand what they are doing. Can someone explain it to me? Or point me to documentation that explains it? My ultimate goal is to build a static Haskell library and make it available to c programmers ignorant of Haskell. The undefines described above are a major obstacle. Does anyone know a way around them? Thanks, Joe Bruce Phone: 509.372.6198 Pacific Northwest National Laboratory 902 Battelle Blvd. Richland, WA
