I found in mk/config.mk.in:

HAPPY_FLAGS    = -agc

I took away the ``c'', but did not get this to propagate to the happy call.
I tried

./Setup clean
./Setup configure ...
./Setup build -v 

and the same with

autoconf
autoreconf
./configure

after make clean --- to no avail:
happy is still called with -agc.

I know nothing about the autotools and the internals of ./Setup ---
what do I need to do to let this change take effect?
