bin/psql compile fails on Redhat 6.0 (glibc 2.1)

bin/psql is now failing to compile on redhat 6.0.
Libc: glibc 2.1
kernel: 2.2.7(and 2.2.5)
compiler: egcs 1.1.2

This is CVS as of today (monday) at 10am(Central Time).
I believe cvs from friday DID compile.

gcc -I../../interfaces/libpq -I../../include -I../../backend   -O2 -Wall
-Wmissing-prototypes   -c psql.c -o psql.o
psql.c:152: initializer element is not constant
psql.c: In function `handleCopyIn':
psql.c:3093: warning: `c' might be used uninitialized in this function
make[2]: *** [psql.o] Error 1
