If I do that, it successfully builds.  I still get a segfault when trying
to compile the ERG:

reading configuration       from `../erg/trunk/ace/config.tdl'
reading types               from `../erg/trunk/ace/../mtr.tdl'
grammar version             ERG (trunk)

Program received signal SIGSEGV, Segmentation fault.

Or when using the pre-compiled grammar:

If it's not clear why these lines could cause a segfault, I will assume
there is a problem with the Windows Subsystem for Linux (it's still
labelled "beta", after all), and I'll try again in a few months.
