function where the error is being reported from. So the WHERE macro now
contains the __FUNCTION__ "macro" and the various js*.c files that use the
WHERE macro to report errors had to be updated too.
Also, the 'access' argument is now being passed as a signed long rather than
unsigned long. Status/return values are often passed in here (e.g. from smblib)
and may be negative. This argument was being displayed with %ld but wasn't
being passed in as a signed value, so on 64-bit long systems, negative numbers
were just printed as large (4M+) numbers.
Also, no need to call getfname() in errormsg() since this is embedded in the
WHERE macro (since 2009).
