dnl This file is included into all any other acinclude file that needs
dnl to use these macros.
 
dnl This is copied from autoconf 2.12, but does calls our own AC_PROG_CC_WORKS,
dnl and doesn't call AC_PROG_CXX_GNU, cause we test for that in  AC_PROG_CC_WORKS.
dnl We are probably using a cross compiler, which will not be able to fully
dnl link an executable.  This should really be fixed in autoconf itself.
dnl Find a working G++ cross compiler. This only works for the GNU C++ compiler.
