  An enumerated type is mixed with another type.

        return ms_fnmatch(pattern, string, Protocol, is_case_sensitive) == 0;

in the function called on return, Protocol was globally defined an 'int' on line 52, instead of 'enum 
protocol_types' (line 1323 of lib/smb.h).

ms_fnmatch() is defined in lib/ms_fnmatch.c line 149:

  int ms_fnmatch(const char *pattern, const char *string, enum protocol_types protocol, BOOL 
is_case_sensitive)

Protocol should probably be defined as 'enum protocol_types'.
