## EHCRT.MAK - Makefile for the C Runtime code for C++ Exception Handling
##
## Targets:
## ========
##
##      ehcrt.lib
##          |
##          +-- throw.obj (throw.cpp) - Handles the 'throw' statement
##          |
##          +-- frame.obj (frame.cpp) - The frame handler, including unwind
##          |                         and handler matching
##          |
##          +-- trnsctrl.obj (trnsctrl.asm) - Transfer of control.
##          |                           Very machine dependant!!!!!
##          |
##          +-- hooks.obj (hooks.cpp) - Initialized variables for callbacks
##          |
##          +-- user.obj (user.cpp) - Callback registration hooks (eg set_terminate())
##          |
##          +-- unhandld.obj (unhandld.cpp) -- Intercept an unhandled exception
##
##
##      all - pseudo target; all of the above.
##
##      clean - pseudo target.  Delete everything from build directory.
##
## Environment:
## ============
##  TPROC ( =i )    Target processor.  i - Intel x86; p7 - Merced; m - MIPS.  No other values supported.
##
##  TOS ( =n )      Target OS.  n - Windows NT.  No other values supported.
##
##  HOST ( =n )     Host OS.  n - Windows NT.  No other values supported.
##
##  VARIANT ( =m )  Library variant:
##                  s - Single-threaded
##                  m - Multi-threaded
##                  d - DLL (Multi-threaded)
##
##  DEBUG ( =1 )    2 - Compile with debug code enabled & debug info,
##                  1 - Compile with debug info only, 0 - no debug info.
##
##  BROWSE ( =1 )   1 - Build browser database, 0 - no browser database.
##
## Build directory is catenation of these options, in this order, eg:
##      innm.11
