+gc/configure.ac: add check for NO_GETCONTEXT definition
+
+This patch is ported from bdwgc package. Since Gauche uses an internal
+copy of the boehm gc code, it is affected by the same problem.
+
+Both configure and configure.ac are modified because autoreconf fails
+due to an incompatibility with the version of the autotools used by
+Buildroot.

+[yann.morin.1998@free.fr: add a comment, change variable name, use
+ AS_IF, remove debug traces, use AC_CHECK_FUNCS (as suggested by
+ Thomas)]
