The option definition in mpg123.c lacked the type specifier (a regression caused by merging). To find that, I added debug.h for more convenient debugs. git-svn-id: svn://scm.orgis.org/mpg123/trunk@175 35dc7657-300d-0410-a2e5-dc2837fedb53

I could do that with variadic macros available:

#define sdebug(me, s) fprintf(stderr, "[" me "] " s "\n")
|

#define debug(me, s, ...) fprintf(stderr, "[" me "] " s "\n", __VA_ARGS__)

Variadic macros are a C99 feature...
|
|
Now just predefining stuff non-variadic for up to $num arguments.
|

It's cumbersome to have them all with different names, though...
