Log Message:
1.0.38.10: Support for building on OpenBSD/PPC (patch by Josh Elsasser).

  * Dynamic space assignments.

  * New Config.* makefile fragment.

  * OpenBSD-specific support in ppc-arch.c and ppc-bsd-os.c

  * Fixed test suite issues relating to OpenBSD/PPC.  This was that the
foreign stack alignment needed setting and that OpenBSD, unlike other
PowerPC targets, requires -fPIC in CFLAGS when building shared objects.

  * It turns out that os_context_sp_addr() in ppc-bsd-os.c is only used
when ARCH_HAS_STACK_POINTER is set, which only occurs on x86oid systems
at the present time.

+;;; Text and data segments start at #x01800000.  Range for randomized
+;;; malloc() starts #x20000000 (MAXDSIZ) after end of data seg and
+;;; extends 256 MB.  Use 512 - 64 MB for dynamic space so we can run
+;;; under default resource limits.
+;;; FIXME: MAXDSIZ is a kernel parameter, and can vary as high as 1GB.
+;;; These parameters should probably be tested under such a configuration,
+;;; as rare as it might or might not be.
