X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=fee6fea7b4bc48061d4509afdfcb15b6f7ce11ce;p=gc

Remove unused HAVE_GETCONTEXT macro definition in configure
(fix of commits 7c13fb8fc, 99134699a)

* configure.ac (getcontext): Replace AC_CHECK_FUNCS to AC_CHECK_FUNC.
* configure.ac [!ac_cv_func_getcontext] (NO_GETCONTEXT): Move AC_DEFINE
to action-if-not-found argument of AC_CHECK_FUNC.
