dnl This was originally from pkgconfig
dnl modified for GnuCash to make it more quiet
dnl in the face of missing config files.
dnl also, pkg-config --errors-to-stdout does not work as advertized on FC3
dnl so we need to redirect stderr to stdout.
dnl PKG_CHECK_MODULES(GSTUFF, gtk+-2.0 >= 1.3 glib = 1.3.4, action-if, action-not)
dnl defines GSTUFF_LIBS, GSTUFF_CFLAGS, see pkg-config man page
dnl also defines GSTUFF_PKG_ERRORS on error
