+modification history
+--------------------
+01h,29apr10,pad  Moved extern C statement after include statements.
+01g,23mar01,sru  add register spacing field to LPT_RESOURCE SPR# 65937
+01f,23aug00,jgn  move _ASMLANGUAGE guard to prevent header file problems with
+                 assembler builds
+01e,04jan00,dat  SPR 29875, chg'd SEMAPHOREs to SEM_IDs
+01d,22nov99,stv  added missing header files (SPR #24014).
+01c,10dec97,ms   added lptResources import
+01b,18oct96,hdn	 re-written.
+01a,13oct94,hdn	 written.
