Revision f725bdb5c704e07578c7bbdd4c853f1e07fd3d16 authored by Thomas Heller on 25 January 2005, 20:46:48 UTC, committed by Thomas Heller on 25 January 2005, 20:46:48 UTC 
Running a bdist_wininst installer, built with Python 2.3, installing
 
for Python 2.4 caused a segfault when post_install_script was used.

The reason was that the file handle passed to PyRun_SimpleFile() was
created with MSVCRT.DLL, but Python 2.4 uses MSVCR71.DLL.

So, I replaced PyRun_SimpleFile() with PyRun_SimpleString().  The
segfault is gone, but the output of the postinstall script doesn't
show up, because still freopen() from MSVCRT is used.

(I would be very gratefull if someone proofreads the patch, at least).

# ----------------------------------
# Don't include <ctype.h> because on OSF/1 3.0 it includes
# <sys/types.h> which includes <sys/select.h> which contains a
# prototype for select.  Similarly for bzero.
#
# A similar problem afflicts HP/UX, but it also hits <sys/time.h>
#
# This test used to merely assign f=$1 in main(), but that was
# optimized away by HP unbundled cc A.05.36 for ia64 under +O3,
# presumably on the basis that there's no need to do that store if the
# program is about to exit.  Conversely, the AIX linker optimizes an
# unused external declaration that initializes f=$1.  So this test
# program has both an external initialization of f, and a use of f in
# main that affects the exit status.
