- **  Filename:       Host.h
+ **  Filename:       host.h
  **  Purpose:        This is the system independent typedefs and defines
  **  Author:         MN, JG, MD
- **  Version:        5.4.1
- **  History:        11/7/94 MCD received the modification that Lennart made
- **                  to port to 32 bit world and modify this file so that it
- **                  will be shared between platform.
- **                  11/9/94 MCD Make MSW32 subset of MSW. Now MSW means
- **                  MicroSoft Window and MSW32 means the 32 bit worlds
- **                  of MicroSoft Window. Therefore you want the environment
- **                  to be MicroSoft Window and in the 32 bit world -
- **                  _WIN32 must be defined by your compiler.
- **                  11/30/94 MCD Incorporated comments received for more
- **                  readability and the missing typedef for FLOAT.
- **                  12/1/94 MCD Added PFVOID typedef
- **                  5/1/95 MCD. Made many changes based on the inputs.
- **                  Changes:
- **                  1) Rearrange the #ifdef so that there're definitions for
- **                  particular platforms.
- **                  2) Took out the #define for computer and environment
- **                  that developer can uncomment
- **                  3) Added __OLDCODE__ where the defines will be
- **                  obsoleted in the next version and advise not to use.
- **                  4) Added the definitions for the following:
- **                  FILE_HANDLE, MEMORY_HANDLE, BOOL8,
- **                  MAX_INT8, MAX_INT16, MAX_INT32, MAX_UINT8
- **                  MAX_UINT16, MAX_UINT32, MAX_FLOAT32
- **                 06/19/96 MCD. Took out MAX_FLOAT32
- **                 07/15/96 MCD. Fixed the comments error
- **                 Add back BOOL8.
