Nothing in these files actually use poll.h Function buffer_fill_and_print() is compiled differently: $ nm --size-sort less3.o less4.o | grep buffer_fill_and_print 00000049 T buffer_fill_and_print 0000004c T buffer_fill_and_print More details are in README file. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29950
