# Perl script to hack AllocReq macros for ELKS bcc compiler
#
# This script rewrites the AllocReq macro which uses ANSI C's '##'
# token pasting operator to an input compatible with the bcc compiler
#
# This is only required if desiring to build client/server Nano-X for ELKS
# To run:
#	mv client.c client.dist
#	./elkspatch.pl < client.dist > client.c
#
