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`.
