4 # BS2000 (Posix Subsystem) hints by Thomas Dorner <Thomas.Dorner@start.de>
6 # Thanks to the authors of the os390.sh for the very first draft.
8 # You can modify almost any parameter set here using Configure with
9 # the appropriate -D option.
11 # remove this line if dynamic libraries are working for you:
14 # To get ANSI C, we need to use c89
15 # You can override this with Configure -Dcc=gcc
16 # (if you ever get a gcc ported to BS2000 ;-).
24 # -D_XOPEN_SOURCE_EXTENDED alters system headers.
25 # Prepend your favorites with Configure -Dccflags=your_favorites

55 Didn't somebody tell you that RISC machines and dynamic library support gives
56 you helluva lot of configuration problems at the moment?
