Description abbott 2005-01-10 14:16:52 UTC 
The -MT option really does use precisely the specified string as the target. 
It would be better if spaces (and other funny characters) were 
escaped (using backslash) in the output. 
 
Note: for my purposes it would be enough to follow the proposal in 
bug #15185 that there be an option to force the full path name in 
the target. 
 
EXAMPLE: compare the outputs of the following two calls to gcc 
$ touch my\ prog.c 
$ gcc -MM my\ prog.c 
my\ prog.o: my\ prog.c 
$ gcc -MM my\ prog.c -MT my\ prog.o 
my prog.o: my\ prog.c 
 
I am inclined to say that the second output is wrong.

What's wrong with -MQ?

Thank you.  I'm at a loss for words: I must be suffering from selective blindness

John.
PS now I wonder why -MT exists at all.

Invalid as explained to use -MQ.
