This sounds good. It would imply broadening the scope of the script beyond just working around the -c -o limitation, but then it was always a curiosity that that has been the *only* issue this script was intended to work around (until now). I'll e-mail the Automake list about this soon. Also: I see that AC_USE_SYSTEM_EXTENSIONS() actually comes from Autoconf. Would that be a good place to put e.g. the -D_UNIX95_THREADS flag needed to get a proper pthreads API? I see that as similar in spirit to -D__EXTENSIONS__. > - Other than that, use documentation.

I can add some information, but am concerned about discoverability. I myself was not aware of this wiki until you mentioned it to me, and I'm already more informed than most people in my org about GNU-related matters. > Reason: > - There are few people trying to build GNU software for z/OS; > therefore communication among you and them should be fairly > simple. True, though the goal should be for the process to be simple/robust enough that e-mail correspondence isn't needed :) > - Autoconf and Automake releases are not frequent these days; > therefore you would have to wait a long time until modified macros > AC_PROG_CC etc. become universally available. This is a good point. Perhaps the wiki can serve as a stopgap measure (it's certainly better than nothing) until these projects release updates. > - What you have written about this environment so far indicates that > there are a lot of complexities; therefore it is likely that you > will have to tweak your recommendations regarding compiler options > and environment variables.

To date, I've been effectively working alone on this platform... --Daniel -- Daniel Richard G. || sk...@iskunk.org My ASCII-art .sig got a bad case of Times New Roman.
