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.
