Re: DLL version of Gnokii for Win32

I think it just specifies extern linkage. In other words, sybols defined as
'extern' are visible outside the module in which they are defined.

Example:

file h.h:
extern int externfunc(void);

file a.c:
#include "h.h"

main()
{
        externfunc();
}

file b.c:
#include "h.h"

int externfunc(void)
{
        return(0);
}

Now it does appear extern linkage is standard but IMHO it does not seem to
hurd. I couldn't find exact definitions for 'extern' however.

Regards,
Feico

Ouch. I just noticed that you use this macro not in the declaration,
but in definition. I don't have ANSI C speficifation with me, but
what's the result of the extern in the function definition? I have
never used such construction.
