I thought it was the job of src/tools/msvc/gendef.pl to generate
.DEF files? In the buildfarm logs I can find lines like:

Generating CITEXT.DEF from directory Release\citext, platform x64
Generating POSTGRES_FDW.DEF from directory Release\postgres_fdw, platform x64

which are emitted by gendef.pl.
