help for compiler error message

[John Cremona <john.cremona@gmail.com>]

I just updated to the latest git head (after the polresultant
business) and find this (after make clean first):

/usr/bin/gcc  -c -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer
 -funroll-loops -fPIC -I. -I../src/headers -I/usr/include -o mpker.o
mpker.c

make[1]: *** [mpker.o] Error 1
make[1]: Leaving directory `/home/jec/pari/Olinux-x86_64'
make: *** [gp] Error 2

It's a while since I last built pari this way, but I'm sure it used to
work.  Any suggestions?  This is with gcc-4.4.3 on ubuntu
2.6.32-41-server.
