;***
;87ctriga.asm - inverse trig functions (8087/emulator version)
;
;   Copyright (c) 1984-89, Microsoft Corporation
;
;Purpose:
;   C interfaces for asin, acos, atan, atan2 (8087/emulator version)
;
;Revision History:
;   07-04-84  GFW   initial version
;   05-08-87  BCM   added C intrinsic interface (_CI...)
;   10-12-87  BCM   changes for OS/2 Support Library
;   11-24-87  BCM   added _loadds under ifdef DLL
;   01-18-88  BCM   eliminated IBMC20; ifos2,noos2 ==> ifmt,nomt
;   08-26-88  WAJ   386 version
;   11-20-89  WAJ   Don't need pascal for MTHREAD 386.
