Yes, yes, I know, I should be using make. We all have a little bit of dinosaur

I love assembler. When in assembler, I'm doing it your way.
I happen to be stuck in batch JCL compiles. I should learn make but it is
never at the top of the critical path.
I know the feeling. I'd love to play with z/OS more, have access, but same
issue.
1. Will make in fact solve this specific problem? Can one readily specify
"global" compiler options for most modules and override them for specific
modules?
Not exactly. #pragma is #pragma and sometimes you just have to bite the bullet and manually surround preprocessor
directives with platform #ifdefs
#ifndef __Z_OS__ /* or whatever is the platform tag for you */
#pragma(foo)
#endif
Classic porting_software_to_myPlatform() pain in the butt. Welcome to the club. I do it all the time because I'm on one
of the less popular open source operating systems
and have to constantly participate in our community porting process.
But once can use make and macros to do all sorts of things that can accomplish
what you are trying to achieve.
2. What's a good learning source for make?
www.oreilly.com/openbook/make3/book/index.csp ?
That's a real good start. That's GNU make, by the way, which is way advanced over Sys V make. So the make command you
have on your system
may have issues with some things that work with GNU.
Happy Thanksgiving! I'm thankful that both hardware platforms and software tools work so much better than they did 30
years ago :)
