[project @ 2001-08-14 13:40:07 by sewardj]
Change the story about POSIX headers in C compilation.
Until now, all C code in the RTS and library cbits has by default been
compiled with settings for POSIXness enabled, that is:
#define _POSIX_SOURCE 1
#define _POSIX_C_SOURCE 199309L
#define _ISOC9X_SOURCE
If you wanted to negate this, you'd have to define NON_POSIX_SOURCE
before including headers.
This scheme has some bad effects:
* It means that ccall-unfoldings exported via interfaces from a
module compiled with -DNON_POSIX_SOURCE may not compile when
imported into a module which does not -DNON_POSIX_SOURCE.
* It overlaps with the feature tests we do with autoconf.
* It seems to have caused borkage in the Solaris builds for some
considerable period of time.
The New Way is:
* The default changes to not-being-in-Posix mode.
* If you want to force a C file into Posix mode, #include as
the **first** include the new file ghc/includes/PosixSource.h.
Most of the RTS C sources have this include now.
* NON_POSIX_SOURCE is almost totally expunged. Unfortunately
we have to retain some vestiges of it in ghc/compiler so that
modules compiled via C on Solaris using older compilers don't
break.
