bug? $(warning)/$(error) evaluated from inside a comment in a 'define'?

[Stephan Beal]

Hi, Makers!

i just discovered a Make behaviour which really surprises me. While that 
in itself is nothing new ;), this one certainly violates the principal 
of least astonishment:

When a $(warning) or $(error) is inside a 'define', it is evaluated even 
if it is part of a comment. A demonstration:

address@hidden:~/cvs/www.t5$ make --version
GNU Make 3.81
...

Input file to reproduce problem:
#!/usr/bin/make -f
##################################################
default: all
define bogo
   # $(warning this should not be evaluated here: (bogo $(1)))
   abc := $(1)
endef
$(foreach ARG,abc def ghi,$(eval $(call bogo,$(ARG))))
all:
##################################################

address@hidden:~/cvs/www.t5$ make -f bug.make
bug.make:11: this should not be evaluated here: (bogo abc)
bug.make:11: this should not be evaluated here: (bogo def)
bug.make:11: this should not be evaluated here: (bogo ghi)
make: Nothing to be done for `default'.

As far as i understand, comments are comments, regardless of the 
context. ???

My assumption is that this also applies to other $(functions) inside 
such a comment, but i haven't tried it out.

Or is this a strange as-designed behaviour?


Many thanks in advance for your time and your awesome product,
(No, that's not sarcasm! i'm a huge fan!)
