# NAME:
|
||
|
|
# fixcpp - fix CPP errors
|
||
|
|
#
|
||
|
|
# SYNOPSIS:
|
||
|
|
# fixcpp [-c][-p patch_file][-b bak_dir][-n new_dir] files(s)
|
||
|
|
#
|
||
|
|
# DESCRIPTION:
|
||
|
|
# For each named file, use sed(1) to fixup any descriptive
|
||
|
|
# text after #else or #endif or that is not properly
|
||
|
|
# commented as this causes ANSI compilers to generate
|
||
|
|
# unnecessary warnings.
|
||
|
|
#
|
||
|
|
# Naturally this script is not guaranteed to be bullet
|
||
|
|
# proof, use of -n or -b is advisable!
|
||
|
|
#
|
||
|
|
# -c causes fixcpp to make sure that only files that
|
||
|
|
# needed changing are affected by returning the original
|
||
|
|
# file to its original location if no changes were needed.
|
||
|
|
#
|
||
|
|
# -p causes fixcpp to append to a patch file the context
|
||
|
|
# diffs of the changes wrought.
