doc cc -c -o

        * doc/autoconf.texi (Limitations of Usual Tools): Note cc may not
        allow -c -o together.

New words:

     `cc -c foo.c' produces a `foo.o' object file.  Most compilers
     allow a `-o' option to direct the output to a different file, but
     POSIX doesn't require this.  `AC_PROG_CC_C_O' can be used to see if
     it works (*note C Compiler::).

Incidentally, I see the "C Compiler" node has some cc notes in
addition to what's under "Limitations of Usual Tools".  Is there a
rule for what belongs where?

If the "C Compiler" node is about language syntax etc, and the
"Limitations" about invocation etc, then perhas the "cc a.c b.c" note
belongs in the latter.
