scan.c:900: warning: ... postgresql-7.1

Does anyone get the same warning messages from postgresql-7.1?

It's under src/backend/parser...

scan.c: In function `base_yylex':
scan.c:900: warning: `yy_cp' might be used uninitialized in this
function
scan.c:900: warning: `yy_bp' might be used uninitialized in this
function

Here is the scan.c line 900
--
register char *yy_cp, *yy_bp;
--

In my previous postgres copy (7.1 beta 4), I did find the initialization
for these two variables in scan.c.

Can anyone please tell me why the init. is removed?  Thank you very
much.
