>Description:
Compile foo.c (below) with "gcc -o foo -save-temps foo.c"  GCC builds foo.i and foo.s but not  object file foo.o. Hence, the exe fails to build.
Here is the verbose output.  Note that although gcc outputs foo.s it sends the tempname  "D:\TEMP/ccSaaaaa.s" to as.exe:

If I repeat the same command (after foo.i and foo.s are built), it outputs a temp .s file and sends it to as.exe to make foo.o and all is fine,

>How-To-Repeat:
Compile the following with "gcc -o foo -save-temps foo.c

/* foo.c * / 
int main()(return 0;}
>Fix:
revert this change:
2001-12-14  Ira Ruben	<ira@apple.com>

	Fix to no allow -save-temps to clobber user's source file.
	* gcc.c: Add static globals input_stat and input_stat_set.
	(do_spec_1): For 'g', 'u', 'U' case with save_temps_flag
	set, check that user's input file is not overwritten.
	(set_input): Reset input_stat_set for each new file.
