+Subject: [PATCH] m4/sctp.m4: make conpatible to autoconf-2.70
+
+On recently released `autoconf-2.70` generated `./configure`
+fails as:
+
+```
+$ ./configure
+...
+checking for struct sctp_event_subscribe.sctp_stream_reset_event... yes
+checking for gcc options needed to detect all undeclared functions... none needed
+./configure: line 16464: syntax error: unexpected end of file
+```
+
+This happens becuase new autoconf generates less whitespace:
+
+```
+{
+if ...
+...
+fi}
+```
+
+It requires at least whitespace between `fi` and `}`.
+
+As input already has newlines the change just drops extra `{}`.
+
+Tested on `autoconf-2.69` and `autoconf-2.70`.
