/* impl.h.mpstd: HARLEQUIN MEMORY POOL SYSTEM TARGET DETECTION
*
* $HopeName: MMsrc!mpstd.h(trunk.23) $
* Copyright (C) 1997 Harlequin Group, all rights reserved
*
* Detect the target platform using predefined preprocessor symbols
* defined by the build environment. The symbols are derived from the
* documentation, or, in the case of GCC, from the compiler itself.
* References to the documentation appear above each detection line.
*
* .hack.align: All alignments have been hacked to be at least 8.
* This is a short term fix to meet req.epcore.attr.align. (some
* of them really ought to be 8, others should be smaller)
*
* .macos.ppc.align: MacOS / PowerPC requires 8 bytes alignment (in
* general). See arch.pp.mac and arch.pp.align.
