It appears that I was incorrect in stating that G 4.9 is the minimum compiler version. It appears that the included version of date (2.2) does not support it. There seems to be a more recent version where it can be built with the -DONLY_C_LOCALE flag.

Status changed from New to Resolved

I tried it out, and it seemed to build properly, but it seems that the use of date::parse in wtdbopostgres causes that error. We could work around that, but maybe supporting GCC 4.9 is not that important. I've updated the minimum version of GCC to 5.0 in the installation instructions, so unless there arises a specific need for GCC 4.9 support, I'll mark this as resolved now.
