* The AC_LANG_PROGRAM macro adds the `main()` so it is erroneous to add it to the test program. * This was detected with the XL compilers which will fail to build the program in this situation. The GNU compiler does not error out or warn, but successfully compiles the program. Signed-off-by: Joshua Hursey <jhursey@us.ibm.com>
