PATCH RFC: Remove OS/2 pexecute support from libiberty
- From: Ian Lance Taylor <ian at airs dot com>

- Subject: PATCH RFC: Remove OS/2 pexecute support from libiberty
OS/2 host support was removed from gcc four years ago:
http://gcc.gnu.org/ml/gcc-patches/2001-02/msg01524.html
There is no OS/2 support in the GNU binutils or in gdb.
However, there is still lingering OS/2 host support for the pexecute
function in libiberty.
I plan to remove it. Any objections?
Ian

* pex-os2.c: Remove.
* configure.ac: Remove *-*-os2-emx* case when setting pexecute.
* Makefile.in (CFILES): Remove pex-os2.c.
(CONFIGURED_OFILES): Remove pex-os2.o.
(pex-os2.o): Remove target.
* configure: Rebuild.
