Patch name: patch.carbon-startup
Authors: Br'fin, Bryce - for MacOSX/Carbon, if you start the app by double clicking in the finder, there is no text console. So in logfunctions::fatal(), display the final message in a Carbon dialog instead of using fprintf. - in the text-mode config interface, return an error code if the user tries to use the text menus when there's no text console. Back in bxmain() this error code causes a panic "Bochs needed the text console, but it was not usable" - if a config file was not found, normally we turn off quick start and drop into the text menus. However in the no-console case the text menus won't work, so we added a panic: Unable to start Bochs without a bochsrc.txt and without a text console. This is a much more useful error than the generic one above. - removed ensure_text_console() which was making matters worse instead of better. Modified Files: logio.cc main.cc gui/siminterface.cc gui/siminterface.h gui/textconfig.cc
