problem building tablefunc in 7.4

The last two times (including a snapshot from about 15 minutes ago)
I tried to build 7.4 with tablefunc I got compiler errors with
the output shown below.
I am running redhat 6.2 as my base distribution.

gcc -O2 -Wall -Wmissing-prototypes -Wmissing-declarations -fpic -I. -I../../src/include -c tablefunc.c -o tablefunc.o
