* cygheap.cc (cygheap_fixup_in_child): Clear cygheap->base so that heap is not

forced to start at the same place in execed process.
* heap.cc: Remove brk* macros for clarity throughout.
* heap.h: Ditto.
* shared.cc (shared_info::initialize): Move heap_chunk test into
heap_chunk_size().
(heap_chunk_size): Check for chunk size here.  Don't go to registry if
heap_chunk_in_mb is already set.
* smallprint.c (console_printf): Add Windows 95 concessions.
