 Ah, indeed, I didn't think about this, sorry. However my (pending) change
at 
https://github.com/wxWidgets/wxWidgets/pull/487/commits/aa7e10bb0919982bfdc510bd9cdc8b84d621d80b
doesn't suffer from this problem.

 So once you update to the wx version using the commit above, you won't
have to do it any more.

 Glad to hear this, I'm almost sure it's the effect of PCH. We really
should stop using them by default in configure, their benefit is not
obvious, to say the least...
