[RFC] s/UINT_MAX/GDB_UINT_MAX/ ?

[Joel Brobecker <brobecker@gnat.com>]

This is the last entity in config/powerpc/xm-aix4.h. The comment says:

/* UINT_MAX is defined in <sys/limits.h> as a decimal constant (4294967295)
   which is too large to fit in a signed int when it is parsed by the
   compiler, so it issues a diagnostic.  Just undef it here so that we
   use gdb's version in defs.h */
#undef UINT_MAX

So we have a collision between the macro defined by GDB and the macro
defined by the system. For recent enough versions of AIX, I don't think
the values are different, so we could look the other way and just remove
the #undef, and all things should work. But we still have this collision
and I think we should fix it.

So I suggest we do an all-source rename of UINT_MAX et al to GDB_UINT_MAX,
or something like this. Unless the collision was expected (ie we want to
pick the system value when defined)?
