make check fails under /poly directory in test release 1.11.90

I see the following failure running 'make check' from the toplevel of 1.11.90:

make  check-TESTS

I see the same problem appear in the 1.11 release.
It runs cleanly in 1.10, but it looks like that's because 1.11 was the
first time the complex_poly code was included in poly/test.c.

This is on gcc (Ubuntu 4.3.2-1ubuntu11) 4.3.2.  Please let me know
what other configure/system information would be useful.
