As described in commit 674a921 ("Add workaround for Win32 wrong type for
size_t"), std::array on Win32 returns type std::size_t, which is
`unsigned int` instead of the `unsigned long` seen on Linux. Calling
std::min requires both arguments to have the same type. On Linux, this
required casting the result of size() to `unsigned` to match the other
input. On Win32, that cast provokes a -Wuseless-cast warning. Add a
workaround by removing the cast and instead explicitly setting the type
of std::min's arguments to `unsigned`, then relying on the compiler to
perform an implicit conversion from `unsigned long` to `unsigned int`
on Linux. The value is always small enough to fit in an `unsigned int`,
so no precision loss will occur.
Field width conversion `.*` always takes an `int`.
On Win32, casting `long` to `int` triggers a `-Wuseless-cast` warning.
Omitting the cast works correctly.
On Linux/amd64, casting `long` to `int` works correctly.
Omitting the cast triggers a `-Wformat` warning.
Add a macro that conditionally expands to `static_cast<int>` or to ``,
as necessary for the target platform.
Most 64-bit systems use `unsigned long` for `uint_fast32_t`. Some
32-bit systems use `unsigned int` for `uint_fast32_t`. To handle this,
write_netgame_profile used casts to `unsigned` and a format string of
`%u`. Switch to inttypes format macros so that the format strings are
correct without requiring a cast to handle systems where `uint_fast32_t`
is not `unsigned`.

Both Primary_weapon and Secondary_weapon should use the underlying enum
type. Primary_weapon uses its enum type now. Secondary_weapon will use
its enum type eventually. Add appropriate casts to newdemo.cpp to keep
it working when those changes are made.
The compiler may or may not recognize that the temporary T{} passed to
make_unique can be omitted. Help it by passing nothing, then explicitly
clearing the returned data as a separate step.
