Subject:	[mingw-runtime bug] gcc2 -Wmissing-prototypes warning in mingw-runtime string.h
Date:	Fri, 28 Feb 2003 19:09:59 -0000
MIME-Version:	1.0

I've run into a problem, compiling some code with
gcc-2 -Werror -Wmissing-prototypes.
There are 3 warnings in mingw-runtime <string.h>:
/usr/include/mingw/string.h:166: warning: no previous prototype for
`strcasecmp'
/usr/include/mingw/string.h:172: warning: no previous prototype for
`strncasecmp'
/usr/include/mingw/string.h:184: warning: no previous prototype for
`wcscmpi'

One simple fix is to add a prototype immediately before the definitions.

Details of the change which added the problem follow.


Max.
