Try using the same compiler and options that 'make' did.  Judging from
http://lists.gnu.org/archive/html/bug-tar/2013-12/msg00027.html
that would be:

cc -qlanglvl=extc89 -qlanglvl=extc99 -g -c foo.c

There is a minor issue here:
'configure' should not be using both -qlanglvl=extc89
and -qlanglvl=extc99, though I don't think the combination
is harmful and I don't think it's causing your problem.
But you might try removing the -qlanglvl=extc89.
