Refactored. Added GECKO_XPCOM_PROGRAM modelled after AC_LANG_PROGRAM but
2006-02-23 Christian Persch <chpe@cvs.gnome.org> * m4/gecko.m4: Refactored. Added GECKO_XPCOM_PROGRAM modelled after AC_LANG_PROGRAM but which produces a program which uses XPCOM; and made GECKO_CHECK_CONTRACTID use this. * configure.ac: Add a check for the gecko typeaheadfind extension. Bug #329118.
