To be pushed in master.
commit b610f43f25aa16d591f6a6b5bf36784050ede651
Author: Akim Demaille <address@hidden>
Date: Sun Aug 19 10:55:08 2018 +0200
examples: check the variant example
* examples/mfcalc/local.mk, examples/rpcalc/local.mk: Define the
programs in a more natural order, source, preproc, then linker.
* examples/test: Be ready to work on programs that are not in
a subdir.
* examples/variant.test: New.
* examples/local.mk: Use it.
* examples/variant.yy: Don't use 0 for nullptr.
Use a more natural output for a list of string.
