The bug report is wrong because with those options, I do not get the warning but reading 
the bug report which is this is forward from, I see that the option -ansi is there, I do not 
know what is should happen when you say '-std=c99 -ansi' or '-ansi -std=c99', should gcc 
put into c89 or c99?  Could some else look at this bug and say what should gcc do?

-ansi means -std=c89.  Which ever comes later of -ansi and -std=c99 should win; this
is the general rule (sadly some exceptions are insisted on).

If -ansi is considered equivalent to -std=c90 or -std=c89, which I believe it is,then I think that one of the following should happen:* The last one on the command line should win.  This is the generalprinciple with conflicting options, I think.* A "conflicting options" error should be produced.Maybe this sort of thing can be cleared up with the options rewrite currently in progress.

Whichever is later should win.  Hopefully this can be addressed with the options rewrite.

The correct command line to use on the test case to trigger trouble is:

cc -ansi -std=c99 -pedantic -Wall
