dnl Check for various support functions needed by the standard

|
dnl Gnome libraries. Sets LIBOBJS, might define some macros,
|
|
dnl and will set the need_gnome_support shell variable to "yes"
|
|
dnl or "no". Also sets up the Automake BUILD_GNOME_SUPPORT
|
|
dnl conditional. This should only be used when building the Gnome
|
|
dnl libs; Gnome clients should not need this macro.
