Changes in the Symantec C++ version 6.11  Library Sources

1. Fixes a bug where _fmsize in some cases would return a smaller value when
        large(~64K)blocks were called for.
2. Fixes a bug where dos_blocksize returned zero always.
3. Adds definition of STKHQQ for Microsoft compatibility.
4. Adds EOF element back to the _ctype array for improved MS compatibility in
        programs which refer to this external variable rather than using the 
        is* functions.
5. Fixes a bug where very large strstream buffers(over 21K) did not work.
6. Fixes a bug where fwrite to stdout and stderr would add 2 CRs(instead of one)
        in front of every line feed.
7. Fixes a problem where the heap would be damaged if there was very little memory
        available at startup, in the NEAR data model programs.
8. Fixes a problem where fmalloc/ffree would receive the wrong value in NEAR
        procedure models.
9.Adds expand, defined equivalent to realloc, for compatibility with Microsoft
        in Windows 16 bit large model. 
10.Fixes creat, dos_creat, and dos_open in the DOSX library to preserve EBX.
