	* hp-symtab.h: New file describing the debug symbols emitted
	by the HP C compilers.
	* hpux-symtab.h: Deleted.

NOTE: hpux-symtab.h was the HP copyrighted description and data structures
for the debug symbols emitted by the various HP compilers (C, C++, Fortran,
Cobol, Pascal, Modula-2, Cobol, etc).

hp-symtab.h is my rewritten version which only describes the debug symbols
used by the HP C compiler.  hp-symtab.h is intended to be copyrighted
