// DESCRIPTION:
//
//   Opens the file for compression.  It handles the case where a READONLY
//   file is trying to be compressed or uncompressed.  Since read only files
//   cannot be opened for WRITE_DATA, it temporarily resets the file to NOT
//   be READONLY in order to open the file, and then sets it back once the
//   file has been compressed.
//
//   Taken from WinFile module wffile.c without change.  Originally from
//   G. Kimura's compact.c. Now taken from shcompui without change.
//
// ARGUMENTS:
//
//   phFile
//      Address of file handle variable for handle of open file if
//      successful.
//
//   szFile
//      Name string of file to be opened.
//
// RETURNS:
//
//    TRUE  = File successfully opened.  Handle in *phFile.
//    FALSE = File couldn't be opened. *phFile == INVALID_HANDLE_VALUE
