Problem: gcc does not understand "-l lib", i.e. the space between
-l and the library name which POSIX.2 permits.

I asked twice on the gcc-bugs mailing list, provided a patch
and changelog and think have done everything imaginable to
comply with procedures. Gerald Pfeifer encouraged my to
open an GNATS PR as a last resort. So here I go. I am
determined to get this patch committed, it's bugging me
ever since. So please give in to my poor soul begging!
You don't want to have an IOCCC winner soon applying for
write access to the repository :-)

How to repeat:

$ cat hello.c 
#include <stdio.h>
#include <math.h>
int main (void) { printf ("hello, world\n%f\n", sin (2.0)); return 0;}
$ gcc hello.c -l m
gcc: m: No such file or directory
$ gcc -v # on FreeBSD 4.1-R
Using builtin specs.
gcc version 2.95.2 19991024 (release)


The patch below fixes this:

$ ./cc hello.c -l m
$ ./a.out          
hello, world
0.909297
$ # Test whether the new error triggers:
$ ./cc hello.c -l  
cc: argument to `-l' is missing

Only a small patch for gcc, but a giant leap for the poor POSIX programmer :-)
