CVS commit: src/usr.bin/make

["Roland Illig" <rillig%netbsd.org@localhost>]

Module Name:    src
Committed By:   rillig
Date:           Sat Aug  8 18:50:12 UTC 2020

Modified Files:
        src/usr.bin/make: var.c
        src/usr.bin/make/unit-tests: counter.exp vardebug.exp

Log Message:
make(1): add debug logging for Var_Parse

This will hopefully help with tracking down why the "Undefined variable"
error message is not triggered.

There is some other non-obvious behavior nearby.  In Parse_DoVar, the !=
assignment operator evaluates the variable using VARE_UNDEFERR, but
there is not even a warning for the following line:

!= echo err ${UNDEFINED} 1>&2
