[PATCH] Use __VA_ARGS__ for all of error's arguments

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Matt Kraai <matt.kraai@xxxxxxxxxxxxxx>

QNX 6.3.2 uses GCC 2.95.3 by default, and GCC 2.95.3 doesn't remove the
comma if the error macro's variable argument is left out.

Instead of testing for a sufficiently recent version of GCC, make
__VA_ARGS__ match all of the arguments.
