This should fix a build failure on ppc64el:

+---
| wop.c: In function 'UG::INT OrderFathersXSH(UG::D3::MULTIGRID*, UG::D3::ELEMENT**)':
| wop.c:16705:60: error: invalid conversion from 'UG::INT (*)(const void*, const void*) {aka long int (*)(const void*, const void*)}' to '__compar_fn_t {aka int (*)(const void*, const void*)}' [-fpermissive]
|   qsort((void *)OE_Map, OE_nBndElem, sizeof(MAP), CompareIDs);
+---

These common spelling errors were found by Debian's lintian tool.

In particular, replace compiler.h by ugtypes, architecture.h,
and ugtime.h. The stuff in compiler.h will from now on be handled
by config.h and friends exclusively.

Because nobody uses that compiler for Apple anymore.  Apparently they never
even did a version for Apples with Intel processor.

That should allow for about one million processors.
When that proves to be insufficient I'll gladly
increase the number again.

Allocate them on the heap instead.  I want't to make the _MAX value
much larger, to accommodate for higher processors numbers.
Allocating arrays of that size on the stack would possibly make
the stack overflow.

Appearently this originated as a backup of wop.c which ended
up in the VCS by accident.  I hasn't been touched since 1997,
and the code compiles happily without it.

move ddd stuff into dimension-dependent namespace.  This is needed for proper 3d parallel support in Dune.  Thanks to Andreas Lauser for the patch

on 64bit architectures (casts from pointer types) with the AutoTools 
build system.  The old build system used to change the definition of INT
for this.  Not having to do this is more elegant, however, because these
casts really only occur at these three places.

Thanks to Bernd Flemisch and Andreas Lauser for the patch.

not as void*. NULL as parameter should still work (because that's what
happened anyway). If you want to pass a number just remove the explicit
cast...
