It is legal for 'pow' to be a macro, therefore the argument list cannot contain preprocessing directives. Make sure pow is a function where this happens (this is a minimal safe fix, the issue only arises in non-performance-critical code.) Signed-off-by: John Bowler <jbowler@acm.org>
This "contrib" directory contains contributions which are not necessarily under the libpng license, although all are open source. They are not part of libpng proper and are not used for building the library, although some are used for testing the library via "make check".
