The Windows implementation of inet_ntop incorrectly omits the `const`
qualifier on the input address. This broke the Windows build, since
Rebirth passes a const-qualified input address, as permitted by POSIX.
Some Windows cross-compilers, such as mingw32, lack a definition of
inet_ntop entirely. For such environments, fall back to inet_ntoa and
disallow building with IPv6.
Rework the formatting and add a Windows-specific test for whether
inet_ntop is available. As inet_ntop is specified by POSIX, assume all
modern non-Windows platforms support it.
Commit b32298df5a ("Rewrite powerup cap
code to centralize logic") centralized powerup cap code in the
powerup_cap_state class.
Commit 901a554e96 ("New powerup management
code: Addeed functions and packet type to ...") removed all use of
powerup_cap_state, but left the dead implementation present.
Commit 479f5ed584 ("Fix 'format specifies
type 'unsigned short' but the argument has type 'unsigned char''
warning") switched the already dead (but still compiled) code from %hu
to %hhu to fix a warning on OS X. Although the commit was written by
Chris, it was my suggestion to use %hhu. I neglected to test Windows
before suggesting it, so the change went in even though Windows does not
accept %hhu; this broke the Windows build. Fortunately, the code had
been dead for 11 months when the change was made, so the fix for Windows
is to remove the long dead code.
x86_64-pc-linux-gnu-g++-6.3 issues a -Wodr diagnostic for the mismatch
between
common/include/3d.h: void _g3_draw_poly(grs_canvas &, uint_fast32_t nv, cg3s_point *const *pointlist, uint8_t color);
similar/arch/ogl/ogl.cpp: void _g3_draw_poly(grs_canvas &canvas, const uint_fast32_t nv, const g3s_point *const *const pointlist, const uint8_t palette_color_index)
The declaration and definition are compatible because `cg3s_point` is a
type alias for `const g3s_point`, so the code worked as it was. Switch
the definition to use `cg3s_point` like the declaration to prevent this
warning and to protect against any future (unlikely) changes to the
definition of `cg3s_point`.
