I believe. This is because:
#define ERRS if (iberrs || ibdebug) IBWARN
So construction like:
if (cond)
ERRS("something");
else
...
, after preprocessor it becomes:
if (cond)
if (iberrs || ibdebug)
IBWARN("someting");
else
...
, and gcc complains about ambiguous else.
To avoid such sort of things I recommended in previous email to wrap
ERRS() macro with do {} while (0):
#define ERRS(fmt, ...) do { \
if (iberrs || ibdebug) \
IBWARN(fmt, ## __VA_ARGS__); \
} while (0)
