Actually, Philippe, that change to pgmain might be the cause of this problem. I just
tried running the latest CVS code with no config file, and it segfaulted. The gdb
backtrace reveals that apparently sscanf() didn't like being passed a NULL string on
line 400 of pgmain.c
The way the line originally was, an empty string was passed to sscanf if the video
mode was not found in the config file. sscanf should simply return without changing
anything. The current version passes a NULL to sscanf, which I think is illegal. I'm
not sure why this fixes the uclinux version, but if it really does fix uclinux and
break other OSes it needs to be #ifdef'ed to pass NULL only when in uClinux.
Frederic changed some of the build system macros for SDL, but nothing in the code has
changed that should break SDL. SDL works fine for me. Make sure you are really loading
the SDL driver with a '-v sdlfb' on the command line.
