[PATCH] ap_spawn_child() under Win32 & mod_rewrite

["Ralf S. Engelschall" <rs...@engelschall.com>]

PR#2483 reports that RewriteMap program still don't work under Win32 because
of a SIGSEGV. The reporter is right, ap_spawn_child_core() calls the child
function with NULL while in the child function the file handles have to be
available. I've assembled the above patch from the reporters description/patch
for testing by our Win32 folks. (I cannot test it myself).

Greetings,
