Changes the following warnings to errors:
C4701: potential use of uninitialized local variable
C4703: potential use of uninitialized local pointer
C4456: declaration hides previous local declaration
C4003: not enough arguments for function-like macro invocation
C4840: use of non-trivial class as an argument to a variadic function
C4805: unsafe mix of bool and int in a numeric operation or comparison
C4305: truncation of double to float or int to bool
C4366: address taken of unaligned field and used as an aligned pointer
C4315: object constructed into an unaligned field with a constructor that expects it to be aligned
Some systems have fseeko but you need to check that off_t is a 64-bit
value (and this requires some magic incantation on some platforms),
others need fseeko64(), Windows has a different symbol, and then some
systems only have an fseek() that's limited to <2GB files.
This is a first step in trying to improve this.
The default mouse was only refenced in the message box gump, which is only used by the recall command in Crusader. The pointing hand cursor in Crusader is an arrow, so it should be acceptable for now.
It appears a lot, and these casts are intentional and look safe.

Unlike the 8-disk version, this one has proper MT-32 resources (see
commit 655afcdf55 for more context).
