	* configure.in: On Windows  platforms, system provided headers are
	  VC++ optimized.  That is, C++ habits are often contaminated into
	  various  headers.  Most  frequent  situation is  the  use of  //
	  comments.  We bypass ANSI  C mode for them.  Otherwise extension
	  libs cannot include those headers.

	* regparse.c (PFETCH_READY):  this  line was to  suppress warning,
	  but  did emit  warnings if  -Wuninitialized was  set.  Assigning
	  NULL instead if pfetch_prev should suffice the situation.
