We explicitly state that win32 users should grab httpd-2.0.44-win32-src.zip
for exactly these sorts of reasons.  BUT...

That is the correct workaround :-)

Well... stay focused, the problem here has nothing to do with the missing
projects that were in the win32-src.zip flavor :-)

The segfault is very simple, we blew it.  That is, we didn't cover our bases
with Win9x when .44 was released.  It will be fixed in .45, but for the
impatient, just replace the file srclib/apr/time/win32/time.c with

http://cvs.apache.org/viewcvs.cgi/*checkout*/apr/time/win32/time.c?rev=HEAD&content-type=text/plain

and you should no longer segfault due to missing WinNT functions on 9x.

Right.  Really easier if you work with recommended source packages
instead of fighting .tar.gz files.

At some point, the apr-iconv tree may also be included with the Unix tarball,
but nobody has really signed off that it would work right now.  That side
of the apr-iconv make system hasn't gotten nearly as much attention, since
Unix can easily include/exclude iconv support using ./configure.
