Unfortunately, no. Gnulib is intended to run on strict C99 and other 
platforms that do not support anonymous unions. There should be no 
trouble sticking with ordinary unions here, as all this stuff is private 
to scratch_buffer and the code is simple either way.

Many of the recently-installed fixes came from Gnulib, and I hope that 
more such fixes will be on the way, so there is a practical advantage to 
staying in sync when that is reasonably easy, as it is here.
