werner@linux-m82i:~/oss/geda/gaf> gsymcheck -vv symbols/io/io-1.sym
gEDA/gsymcheck version 1.5.1.20081221
[...]
Warning: Found the same number in a pinnumber attribute and in a net 
attribute [1]

No errors found

The message changed in the current git version of gsymcheck.
Use gsymcheck only as an advisor, not a dictator.
