>Description:
When using -e to override variable values using environment variables, -V still prints the non-overridden value.
The man page for -V says "Print bmake's idea of the value of variable, in the global context." Maybe the behavior of -V when using -e is subtly correct given that wording. But the behavior is perhaps surprising for some at least.
>How-To-Repeat:
% printf 'X=2\nx:\n\t@echo "MAKE_VERSION: ${MAKE_VERSION}."\n\t@echo "X: $X."\n\t@echo "Y: $Y."\n' > /tmp/mf
% env X=xe Y=ye /usr/local/bin/bmake -e -f /tmp/mf
MAKE_VERSION: 20220928.
X: xe.
Y: ye.
% env X=xe Y=ye /usr/local/bin/bmake -e -f mf -V X -V Y
2
ye
Notice that '-V X' shows '2' instead of 'xe'.
>Fix:
No fix to source code nor documentation yet.
This could be considered to not be a bug and perhaps just the documentation should be more clear.
