Probably after merging #399, autogen.sh generates this code here:
```
  if test "$cross_compiling" = yes; then
  else
  cat >conftest.$ac_ext <<_ACEOF
```
ie. else immediately following then. On other systems, there is : (true) there. @theuni Do you have an idea?

This has been open forever without any other reports, I assume it got fixed. Feel free to reopen if otherwise.

CentOS release 6.7 (Final)
elichai commented at 8:47 AM on May 18, 2020: contributor

I confirmed it in a docker, the problem is that CentOS 6 ships with an old autoconf, and after installing a third party update I was able to compile and pass the tests. CentOS 6 got released a decade ago, stopped getting full updates 3 years ago and will be officially unmaintained in a few months. The result of that is that I couldn't even clone this repo, because yum install git gave me 1.7.1, which github doesn't support, so I had to get git from a third party source.

So I think that not supporting CentOS 6 out of the box is quite reasonable seeing that even github doesn't support it out of the box (oh, and don't get me started on the SSL problems I had because all the CAs are out of date and it uses old openssl which I had to upgrade both)

Yes, no need to support old very old versions of autoconf. But I assume the fix is trivial. @paveljanik @duhanov @elichai Can you check if #752 fixes this issue?
