WDSP_FPE_GUARD: the macro is defined only in linux_port.h under
#if defined(linux)||defined(__APPLE__). On the _WIN32 path it was
completely undefined. Added a fallback no-op definition in comm.h
guarded by #ifndef so it applies to Windows (and any future platform
that doesn't include linux_port.h).
volatile int* vs volatile LONG*: Win32 Interlocked functions expect
volatile LONG* (= volatile long*). The dispatcher field is volatile int.
On Windows LLP64 both are 32-bit so the operation is correct, but GCC 14
promotes this mismatch from warning to error. Suppressed with
-Wno-incompatible-pointer-types in Makefile.windows, consistent with
how MSVC handles it silently.

On Linux (case-sensitive filesystem) MinGW-w64 installs the header as
windows.h (lowercase) while comm.h included <Windows.h> (capital W),
causing a fatal compile error when cross-compiling for Windows.
Changed to <windows.h> which works on both Linux/MinGW-w64 and native
Windows/MSVC (Windows header includes are case-insensitive on NTFS).
