Get httpd-2.1 building once again on win32.

NEVER NEVER screw around with redeclaring AP_ macros and constants.
  If the compiler won't pick them up, e.g., AP_DECLARE, ya've done 
  something wrong from the start.

  All httpd/ap headers depend on httpd.h - plain and simple, so this
  un-convolutes the unusual order here.

  STATIC has become PCRE_STATIC, along with some other odd definitions.
  The only remaining emit is that _pcre_free export is imported, which
  implies something is unusual with the declaration.  Still researching.
