I cannot reproduce this in my GCC 7.3 even in C++11 mode (by default it
compiles in C++17 with CMake build). Please check if this helps:
This helps indeed.
Committed.
By the way, what is the oldest supported GCC? README says it is GCC 4.7. Is
it right?
I think that for LyX 2.4 is reasonable to bump at least to gcc 4.8, because
4.7 does not have full support for C++11 yet. I am personally compiling
with 4.9, so unless someone trumps me with lower version we should state
4.9 in README.

It was 4.7 in README and 4.8 in INSTALL, so I bumped it to 4.9 everywhere :)
+1
we should also mention it in lib/RELEASE-NOTES.

I'm not sure about section to add this. Please amend the attached patch.
