# Translate XCOMM into pound sign with sed, rather than passing -DXCOMM=XCOMM
# to cpp, because that trick does not work on all ANSI C preprocessors.
# Delete line numbers from the cpp output (-P is not portable, I guess).
# Allow XCOMM to be preceded by whitespace and provide a means of generating
# output lines with trailing backslashes.
# Allow XHASH to always be substituted, even in cases where XCOMM isn't.
