From: Johannes Schindelin <johannes.schindelin@xxxxxx>
In 08809c09aa13 (mingw: add a helper function to attach GDB to the
current process, 2020-02-13), I added a declaration that was not needed.
Back then, that did not matter, but now that the declaration of that
symbol was changed in mingw-w64's headers, it causes the following
compile error:
CC compat/mingw.o
compat/mingw.c: In function 'open_in_gdb':
compat/mingw.c:35:9: error: function declaration isn't a prototype [-Werror=strict-prototypes]

Let's just drop the declaration and get rid of this compile error.
