| 15 | dnl FIXME: We temporarily define our own version of AC_PROG_CC. This is | |
| 16 | dnl copied from autoconf 2.12, but does not call AC_PROG_CC_WORKS. We | |
| 17 | dnl are probably using a cross compiler, which will not be able to fully | |
| 18 | dnl link an executable. This should really be fixed in autoconf | |
| 19 | dnl itself. | |
