2000-04-21 Garry R. Osgood <gosgood@idt.net> * app/main.c * libgimp/Makefile.am * libgimp/gimp.c * libgimp/gimpsignal.c (New ) * libgimp/gimpsignal.h (New ) Patch by Austin Donnelly <austin@gimp.org> to address #2742. (I took the liberty of moving it to libgimp for general consumption, & fixed a typo) Thanks due to Tim Mooney <mooney@dogbert.cc.ndsu.nodak.edu> for testing this on various flavors of OSF/1 boxes where #2742 seemed especially common.
