[GCC][PATCH] Fix ada compile error on Windows x86_64 (committed as r241907 under the obvious rule)

[Tamar Christina]

Hi all,

The changes in r240999 re-arranged includes and
left out signal.h for Windows x86 builds.

This breaks the build and prevents GCC builds from
completing with messages such as:

adaint.c:3317:19: error: 'SIGINT' undeclared (first use in this function); did 
you mean 'SAIT'?

    else if (sig == SIGINT)
                    ^~~~~~

Bootstrapped successfully on x86_64-w64-mingw32.

Committed as r241907.

Thanks,
Tamar
