[Bug target/39063] New: libgcc2.c:mprotect() for mingw, incompatible pointer type warning

["sezeroz at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

in windows replacement of mprotect() in libgcc2.c uses VirtualProtect
which requires an unsigned, not a signed ptr as its last argument. the
attached patch fixes a 'may be used uninitialized' warning, too.
here are the warnings:
../../../gcc-svn/libgcc/../gcc/libgcc2.c: In function 'mprotect':
../../../gcc-svn/libgcc/../gcc/libgcc2.c:2079: warning: passing argument 4 of
'VirtualProtect' from incompatible pointer type
/opt/buildroot/gcc-svn/winsup/mingw/include/winbase.h:1126: note: expected
'PDWORD' but argument is of type 'int *'
../../../gcc-svn/libgcc/../gcc/libgcc2.c:2064: warning: 'np' may be used
uninitialized in this function
