Consider the following:
static void ne_cmn_err(dev_info_t *, int, const char *, ...);
#define ne_error(dip, format, ...) \
ne_cmn_err((dip), CE_WARN, (format), __VA_ARGS__)
If issued without varargs, the preprocessor incorrectly expands the
ne_error macro as:
ne_cmn_err(dip, level, format, ); /* note extraneous comma */
Odd... I seem to recall this working just fine on studio 12 - is this a
limitation of 11 or am I missing something?
