Subject:	Warning in a cygwin header when using both -Wall and -W
Date:	Wed, 14 May 2003 16:42:02 +0200
MIME-Version:	1.0

Hi,

The following code generates a warning for cygwin/cygwin_dll.h when _both_ 
-Wall and -W are specified at the same time:

------8<------
#include <cygwin/cygwin_dll.h>

DECLARE_CYGWIN_DLL(DllMain);
------8<------

Say, the code above was saved to a file test.c. The warning can be seen when 
using a command line like:
gcc -c test.c -Wall -W

It is caused by this code in cygwin/cygwin_dll.h:
static int __dllMain (int a, char **b, char **c)      \
{      \
  return Entry (storedHandle, storedReason, storedPtr);              \
}      \

However, it can easily be avoided by changing that code into:
static int __dllMain (int a, char **b, char **c)      \
{      \
  (void) a; \
  (void) b; \
  (void) c; \
  return Entry (storedHandle, storedReason, storedPtr);              \
}      \

If you reply, please send a carbon copy to dbjh AT gmx DOT com as I'm not a 
member of this mailing list.

Kind regards,
Daniel Horchner
