# This python script wraps gcc-mp-4.X so it can handle
# compilation options memcheck uses on Mac, including:
#  a) skip "-arch XXX"
#  b) define empty "__private_extern__" macro so it doesn't bark
#     on mac-specific code using this keyword.
#  c) skip "-mno-dynamic-no-pic" and "-mdynamic-no-pic"
#     This may not be a very clean solution in general but it works.

# The gcc command should be passes as an environment variable,
# e.g. GCC_BINARY_MASK=/opt/local/bin/XXX-mp-4.4
