>Description:
The driver has a bug that prevents it from deleting incomplete object files on pressing Ctrl+C. This happens ONLY when not using a space betwen "-o" and the file name (e.g.
"-ofile.o"). This is very easy to reproduce by generating a large .c file (I did it with a simple shell script) and while it compiles, press Ctrl+C. The file.o file will remain; this is bad since it confuses make.

I've tracked the problem: it is in gcc.c when executing the 'W' spec, it calls add_temporary_file_name or such (don't remember the exact function name, don't have the sources handy). The name that is passed to the function includes the -o switch (e.g. add_temporary_file_name ("-ofile.o")) and on failure the driver tries to delete the file with this name, and naturally fails.
>How-To-Repeat:
gcc -c -ofile.o file.c
>Fix:
Not sure, this requires deep knowledge of how specs are parsed and executed. A quick-and-dirty patch is possible, but I presume whoever knows the internals will do it a lot better.
