????-??-?? Keith Marshall <keithmarshall@...>
Support pragmatic identification for w32api source directory.
* aclocal.m4 (MINGW_AC_W32API_SRCDIR): New macro; implement it.
* configure.in (W32API_INCLUDE): Assign using MINGW_AC_W32API_SRCDIR.
* Makefile.in (W32API_INCLUDE): Prefix -I flag to AC_SUBST value.
* mingwex/Makefile.in (W32API_INCLUDE): Likewise.
* profile/Makefile.in (W32API_INCLUDE): Likewise.
