#57333: xorg-server-devel @1.20.1 does not build on Mac OS X 10.5.8, Leopard,

Comment (by ballapete):

 This is interesting! When I use `-ansi` to be closer to `GCC 2.95`
 compilation stops at the same spot where `GCC 6` stops. When I am using
 `-std=c99` it stops with exactly the same `CARD32` error.

 This `CARD32` error comes from the C preprocessor. It turns in
 `randr/randrstr.h` the statement

 {{{
 typedef XID RRLease;
 }}}

 into

 {{{
 typedef XID CARD32;
 }}}

 Cause is that `/opt/local/include/X11/extensions/randrproto.h` is included
 which has

 {{{
    48   #define RROutput CARD32
    49   #define RRMode CARD32
    50   #define RRCrtc CARD32
    51   #define RRProvider CARD32
    52   #define RRModeFlags CARD32
    53   #define RRLease CARD32
 }}}

 Why are

 {{{
 typedef XID RRMode;
 typedef XID RROutput;
 typedef XID RRCrtc;
 typedef XID RRProvider;
 }}}

 not processed? Anyway, we could try a patch à la

 {{{
 +#if __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ >= 1060
  typedef XID RRLease;
 +#endif
 }}}

 and see whether compilation goes further. No error happens. Here. A new
 one comes up:

 The code here is:

 {{{
   123   #ifdef __APPLE__
   124   #include <AvailabilityMacros.h>
   125
   126   static char __crashreporter_info_buff__[4096] = { 0 };
   127
   128   static const char *__crashreporter_info__ __attribute__
 ((__used__)) =
   129       &__crashreporter_info_buff__[0];
   130   #if MAC_OS_X_VERSION_MIN_REQUIRED >= 1050
   131   // This is actually a toolchain requirement, but I'm not sure the
 correct check,
   132   // but it should be fine to just only include it for Leopard and
 later.  This line
   133   // just tells the linker to never strip this symbol (such as for
 space optimization)
   134   asm(".desc ___crashreporter_info__, 0x10");
   135   #endif
   136   #endif
 }}}

 Why not leaving this for `Snow Leopard` and later? Because who woul read
 crash reports from `Leopard`? Something like

 {{{
 -#if MAC_OS_X_VERSION_MIN_REQUIRED >= 1050
 +#if MAC_OS_X_VERSION_MIN_REQUIRED >= 1060
 }}}

 should allow the build to enter the unknown…
