compile APR with MinGW

[Guenter Knauf <fu...@apache.org>]

Hi,
I've just tried to compile APR-HEAD with latest MSYS/MinGW, and so far 
buildconf + configure worked (tried with recent snapshot, not yet tested 
from SVN); compilation though breaks then in waitio.c:
/bin/sh /home/Administrator/apr/libtool --silent --mode=compile gcc -g 
-O0   -DHAVE_CONFIG_H -DWIN32 -D_LARGEFILE64_SOURCE   -I./i
nclude -I/home/Administrator/apr/include/arch/win32 
-I./include/arch/unix -I/home/Administrator/apr/include/arch/unix 
-I/home/Admi
nistrator/apr/include -I/home/Administrator/apr/include/private 
-I/home/Administrator/apr/include/private -I/home/Administrator/ap
r/xml/expat/lib -o support/unix/waitio.lo -c support/unix/waitio.c && 
touch support/unix/waitio.lo
support/unix/waitio.c: In function 'apr_wait_for_io_or_timeout':
support/unix/waitio.c:80:20: error: 'apr_file_t' has no member named 
'pollset'
support/unix/waitio.c:82:44: error: 'apr_file_t' has no member named 
'pollset'
support/unix/waitio.c:86:24: error: 'apr_file_t' has no member named 
'pollset'
make[1]: *** [support/unix/waitio.lo] Error 1
make[1]: Leaving directory `/home/Administrator/apr'
make: *** [all-recursive] Error 1

looking at include/arch/win32/apr_arch_file_io.h the pollset member now 
depends on APR_FILES_AS_SOCKETS=1:
http://svn.apache.org/viewvc?view=revision&revision=748080
while APR_FILES_AS_SOCKETS=0 from apr.h ...
so does it make sense at all to compile support/unix/waitio.c for win32, 
or should we exclude WIN32 platform?

(did here replace OS2 exclude because Brian seems to have added now an 
own implementation support/os2/waitio.c ...)

BTW. r748080 was not yet backported to APR 1.x so this prob exists only 
with HEAD ...
