# patch52: created
#

# Thank you HP-UX for having a cpp that strips trailing backslashes in the
# text. As of today, you are the only reason for this program to exist.
# People designing such things should have their hands cut off to prevent
# them from doing further damage :-)
#
# This program is meant to be called from jmake. All it does is pre-process
# the file it is given as argument, focusing on #include directives and
# resolving them as cpp would (but without the #line stuff since we don't
# really care about it), escaping all the trailing \ into '\ ^M'. The resulting
# temporary file is then handed off to the real cpp for macro processing, and
# the output is printed on stdout, after restoration of any original trailing \.
# Again, thanks HP-UX for making this so challenging and exciting... :-)
#
# Note that we MUST leave alone all the trailing @!\ or @@\, since those appear
# in macros and must go away some way or the other. Also trailing backslashes
# on #define lines are really continuations and are left un-escaped.
