4 # This stuff is written in C (and cannot be written in Haskell).
5 #
6 # .c files are vanilla C,
7 # .hc files are "Haskellized-C", compiled using the C compiler and
8 # (possibly) the assembly-mangler. The GHC driver script
9 # knows how to compile this stuff.
10 #
11 # Other sorta independent, compile-once subdirs are:
12 # gmp -- GNU multi-precision library (for Integer)
