* Module Name: WSPDUMP.C
*
* Program: WSPDUMP
*
*
* Description:
*
* Dumps the contents of a WSP file.
*
* Contitional compilation notes:
*
* Modification History:
*
* 6-12-92: Adapted OS/2 version of wspdump for NT marklea
* 6-17-92: Modified wspDumpBits to dump in correct order marklea
* 6-18-92: Added page useage information marklea
* 8-31-92: Made single exe from wspdump, wsreduce and wstune marklea
* 4-13-98: QFE DerrickG (mdg):
* - new WSP file format for large symbol counts (ULONG vs. USHORT)
* - support for long file names (LFN) of input/output files
* - removed buggy reference to WSDIR env. variable
* - based .TMI file name exclusively on .WSP name for consistency
* - removed limit on symbol name lengths - return allocated name from WsTMIReadRec()
* - removed unused static declarations
*
