* xtrans: silence compiler warning regarding is_numericUlrich Sibiller2016-11-032-1/+4

* Fixed #ifdef checks that were using i386 to use __i386__Jeremy Huddleston2016-11-023-11/+11
| | | | | | | | | | | | | | | | | """ It's simply obsolete, sloppy, compiler namespace pollution. The compiler is not allowed to predefine symbols that might conflict with ordinary identifiers. For backwards compatibility gcc currently predefines i386 when compiling for x86 32-bit (but not 64-bit), but that will go away. It is also not defined if you specify -ansi when invoking the compiler, because then it is seriously standards compliant. Other compilers shouldn't define it either. Correct code shouldn't rely on it being defined. However __i386__ is safe and proper. """ Backported-to-NX-by: Ulrich Sibiller <uli42@gmx.de>

* Xlib.h: Fix macros imitating C functions.Dominik Muth2016-10-191-17/+17
| | | | | | | | | | | | | | | | | | The basic rule "put parantheses around macro parameters" should be observed where possible. Otherwise code like ConnectionNumber(foo = bar); fails to compile. (It obviously passes if ConnectionNumber is a C function.) There are several other macros amended for the same reason. This bug appeared while building http://ioccc.org/1993/cmills.c, so historically it was not present.

* XKB: fix XkbGetKeyboardByName with Xming serverOlivier Fourdan2016-10-191-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | XkbGetKeyboardByName relies on flags to read the data from the server. If the X server sends us the wrong flags or if a subreply is smaller than it should be, XkbGetKeyboardByName will not read all the available data and leave data in the buffer, which will cause the next _XReply() to fail with: [xcb] Extra reply data still left in queue [xcb] This is most likely caused by a broken X extension library [xcb] Aborting, sorry about that. xcb_io.c:576: _XReply: Assertion `!xcb_xlib_extra_reply_data_left' failed. Aborted Check if there is some extra data left at the end of XkbGetKeyboardByName() and discard that data if any is found.
