AC_PREREQ(2.12)
AC_INIT(dllmain.c)
dnl FIXME: We temporarily define our own version of AC_PROG_CC. This is
dnl copied from autoconf 2.12, but does not call AC_PROG_CC_WORKS. We
dnl are probably using a cross compiler, which will not be able to fully
dnl link an executable. This should really be fixed in autoconf
dnl itself.
