+DESCRIPTION
+
+This file contains basic platform definitions used to write portable (O/S-
+independent) code.  
+
+By convention, this should be the only file in a set of "portable" code which
+contains #ifdef's and other constructs used to accomodate machine or O/S
+dependencies.

+ * Structure packing
+ *
+ * By convention, all code wants "zero-byte packing".  That is, the compiler
+ * should assemble structures so that fields are contiguous in memory...no
+ * padding should be added.  CMC's use of this convention was approved by
+ * D'Anne Thompson of WRS on 09jun99.
