New version: (has to be indented?)
AC_CHECK_FUNC([getcwd], AC_DEFINE([HAVE_GETCWD],[1],[Define to 1 if you
have the `getcwd` function]))
if test x"$ac_cv_func_getcwd" == xyes; then
AC_MSG_CHECKING([getcwd(NULL,0)])
AC_RUN_IFELSE([
AC_LANG_PROGRAM([
#include <unistd.h>
],[
char *result = getcwd(NULL,0);
if (result == NULL)
return 1;
])],[
AC_MSG_RESULT([yes])
AC_DEFINE([HAVE_GETCWD_GLIBC], 1, [Define to 1 if you have support for
`getcwd(NULL,0)`])
],[
AC_MSG_RESULT([no])
],[
AC_MSG_NOTICE([cannot run test program while cross compiling])
])
