I'm not subscribed to the smpeg list any more (for many months), so I'm not
quite sure why I got this message. However...
It is no longer necessary to double-parenthesize macros with a variable number
of parameters. Macros can accept a variable length argument list. Define
SMPEGDBG as follows and then you can just replace printf with SMPEGDBG:
#define SMPEGDBG(x...) printf(x)
int main(int argc, char * argv[])
{
SMPEGDBG("Hello world. Look ma, no arguments!\n");
SMPEGDBG("This is a usage with one (%d) argument.\n", 1);
return 0;
}
