# IBM_PROLOG_END_TAG
# The purpose of this script is to convert a series of GCC compiler
# flags into an equivalent series of flags, but which use absolute
# paths for include directories (i.e. the "-I" flag) instead of
# relative paths. We have to do this when GCOV is in use, because it
# stupidly puts data files in one path but stores paths inside the
# data files that are relative to some other path. When GCOV then
# tries to read the source files via these relative paths, it can't
# find the files. We correct this by converting all paths to source
# and header files to absolute paths.
