Apparent GCC 2.95.2 bug(s): -std documentation; using -std= with -ansi

[pfaffben at msu dot edu (Ben Pfaff)]

There seem to actually be two bugs that I've found.  First, the
Info documentation, in node "C Dialect Options", says that
-fstd=... is a gcc option, but the actual option appears to be
-std=...; note lack of `f'.

Second, gcc doesn't seem to like -std=ID where ID is not a gnu*
option to be used along with -ansi.  Maybe these options aren't
supposed to be used together, but in that case I think that the
error message should be better:

blp:~/tmp(0)$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.2/specs
gcc version 2.95.2 20000313 (Debian GNU/Linux)
blp:~/tmp(0)$ cat > test.c
int main (void) { return 0; }
blp:~/tmp(1)$ gcc -fstd=iso9899:199x test.c
cc1: Invalid option `-fstd=iso9899:199x'
blp:~/tmp(1)$ gcc -std=iso9899:199x -ansi test.c
test.c:0: malformed option `-D __STRICT_ANSI__-trigraphs'
blp:~/tmp(1)$ gcc -std=iso9899:199x test.c
blp:~/tmp(0)$ 

I think that the problem is probably related to code like lines
616-617 from gcc.c in 2.95.2:
                  %{ansi|std=*:%{!std=gnu*:-trigraphs -D__STRICT_ANSI__}}\
                  %{!undef:%{!ansi:%{!std=*:%p}%{std=gnu*:%p}} %P} %{trigraphs}\
but I'm sure you're more of an expert on this than I am ;-)
