[Bug preprocessor/16323] New: -Wendif-labels listed even though it's on by default

[Bug preprocessor/16323] New: -Wendif-labels listed even though it's on by default

[sebor at roguewave dot com]

The gcc manual lists warning options that are not the default. Since the
-Wendif-labels option is listed, the default must be -Wno-endif-labels.
However, gcc 3.4 issues this type of a warning even with no options at
all. Either gcc or the manual must be wrong.

$ cat t.cpp && gcc --version && gcc -c t.cpp                     
#if FOO
#endif FOO
