I'm seeing the same issue, with gcc from debian unstable ("gcc (Debian 4.3.2-1)
4.3.2").
The problem appears either when a 'gcc' directory (other than the "real" gcc
directory) is found through the PATH, or else GCC_EXEC_PREFIX is set to a path
other than the "real" gcc path.
So, here are all kinds of ways I'm able to reproduce, assuming hello.c as
above:
(1) with a 'gcc' subdir alongside hello.c:
PATH=.:$PATH gcc hello.c
(note, however, the order is important: "PATH=$PATH:." works fine...)
(2) with a 'gcc' subdir in .. :
PATH=..:$PATH gcc hello.c
(3) with a 'gcc' subdir in /tmp:
PATH=/tmp:$PATH gcc hello.c
(4) regardless of the existence of a 'gcc' subdir:
GCC_EXEC_PREFIX=/tmp gcc hello.c
(5) the "real" gcc path is /usr/lib/gcc. However, this still fails:
GCC_EXEC_PREFIX=/usr/lib/gcc gcc hello.c
(6) OTOH, this works fine (note the trailing slash):
GCC_EXEC_PREFIX=/usr/lib/gcc/ gcc hello.c
Below are two samples of the output, for (5) and for (1):
$ GCC_EXEC_PREFIX=/usr/lib/gcc gcc -v -save-temps hello.c
Using built-in specs.
