While the change for Tor seems a good idea irrespective of the error 
message from TCC (purely from a code cosmetic perspective) it is correct 
ISO C in usual implementations (when an enum containing a negative member 
is compatible with 'int').  IOW TCC gave the error message incorrectly.

A related error message when the respective function would have been 
redeclared with type 'unsigned' (but same enum at the other decl) is 
correct, though.

All fixed in latest mob.  Many thanks for the report!
