gmake doesn't produce err mesg when it should

[Gabriel Zachmann]

Why doesn't gmake produce an error message
when I write a $(call blub,...) of a "function" blub which doesn't exist?

And why doesn't gmake produce an error message
when I write $(wildacrd ...) which is a function which doesn't exist?

It just silently "ignores" these errors!

These things have caused me hours of searching for bugs ;-(

Note that it would be possible for gmake to detect these errors:
an expression $(something ..), where 'something' is followed by a space,
cannot be a make variable.

In the case of $(call blub,...) when 'blub' doesn't exist (yet),
it would be nice to have the option of having make produce a warning.
In the case of "built-in" functions like $(wildacrd ...),
it is always an error, I think.
