dnl FIXME: We temporarily define our own version of AC_PROG_CC. This is
|

|
|
dnl copied from autoconf 2.12, but does not call AC_PROG_CC_WORKS. We
|
||
|
|
dnl are probably using a cross compiler, which will not be able to fully
|
||
|
|
dnl link an executable. This should really be fixed in autoconf

dnl itself.
