著名Awk语言的编译器

Note added June, 2002:  

With the advent of OS X, life is simpler:  if you have the developer
tools installed, the standard awk makefile and gcc works fine, and
you can ignore the rest of this file, which is now hereby deprecated.




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.
