Fix throw_winerror_with_name build error on x86-64 Cygwin
The GDB build currently fails on x86-64 Cygwin, with:
src/gdbsupport/errors.cc: In function ‘void throw_winerror_with_name(const char*, ULONGEST)’:
src/gdbsupport/errors.cc:152:12: error: format ‘%d’ expects argument of type ‘int’, but argument 3 has type ‘ULONGEST’ {aka ‘long unsigned int’} [-Werror=format=]
152 | error (_("%s (error %d): %s"), string, err, strwinerror (err));
| ^
Fix this by adding a cast. While at it, the error codes are really a
DWORD that results from a GetLastError() call, so I think unsigned is
more appropriate. That is also what strwinerror already does:
sprintf (buf, "unknown win32 error (%u)", (unsigned) error);
The cast is necessary on MinGW GDB as well, where ULONGEST is unsigned
long long, but for some reason, I don't get a warning there.
