This file contains a make shell script and a version
of the file missing95.c for the Mac, courtesy of
Dan Allen.

make shell script:

# MPW Shell script to build Awk using Apple's MRC compiler.
# 22 Jan 1999 - Created by Dan Allen.
# 25 Mar 1999 - Updated for newer Awk.
#
# Porting notes for the Mac:
#
# 1.  main in main.c needs to have its prototype changed to:
#
#     int main(int argc, char *argv[], char *environ[])
#
# 2.  popen and pclose in missing95.c need to have as their body the
#     older style
#
#				return NULL;
#
#     as parallel pipes are not supported by MPW.
#
# 3.  To make your Mac more responsive while long awk scripts run,
#     you may want to add some SpinCursor calls to support cooperative multitasking.
#
# All of these minor changes can be put under "#ifdef powerc" for portability's sake.
