2002-11-06 Sven Neumann <sven@gimp.org> * app/base/base.c (base_init): don't say we'd use MMX if it is disabled. * libgimpmodule/gimpmodule.[ch] * app/gui/module-browser.c: changed enum values and user-visible strings to saner values. * libgimpmodule/gimpmoduledb.c * plug-ins/tools/tool-safe-mode.c: made them less verbose.
