Re: [Python-Dev] report on building of python 2.5.2 under msys under wine on linux.
hiya roumen, good to hear from you - i've been merging in the work
that you did, on mingw native-and-cross compiles. got a couple of
questions, will post them in the bugreport ok?

ah, that might be worth trying. thank you!

oh don't get me wrong - it all works, all compiles absolutely fine,
modules and everything...
it just... _feels_ like a cross-compile, because of msys.
you're sort-of in unix-land, yet the resultant binary python.exe
is most _definitely_ "c:/"ey.

i have 12 that fail - but if i replace msvcrt builtin with msvcrt
native, all but two or three disappear. the S8I one (which is due to
gcc, you already found that i noticed); tmpfile() tries to write to
z:/ which is of course / - the root filesystem; and
os.environ['HELLO'] = 'World; os.popen("/bin/sh echo $HELLO").read()
!= 'World' but i'm not sure if that one _should_ succeed: the only
reason it got run is because i _happened_ to have msys installed.

oh i noticed in http://bugs.python.org/issue3871 that you replaced
some of the math functions.

ooo, scarey.
oh! roumen, very important: martin says we have to be _really_
careful about releases of mingw-compiled python.exe and
libpython2.N.dll - they _have_ to match up with the python-win32 build
msvcrt otherwise it will cause absolute mayhem.
i'm currently adding an msvcr80 specfile so i can build under wine -
see http://bugs.python.org/msg79978 which requires that you customise
wine to get it to drop something blah blah don't care in the least, i
just want it all to work :)
