Build failure on Linux - strnicmp undefined

[Fernando Nasser <fnasser at cygnus dot com>]

The following change prevents GDB to build on Linux machines (and perhaps
others) where "strnicmp()" is not defined.

Note that the ChangeLog entry has the wrong date.  It was checked in this 
morning.

I reverted it in my sandbox.  If we can't get hold of Pierre because of
time differences I will revert the patch in the repository as well.


revision 1.2
date: 2000/12/01 10:40:10;  author: muller;  state: Exp;  lines: +22 -16

        * p-exp.y (yylex): avoid problem with symbol name
        starting as a operator name.



Here is the build error:
