-Wno-missing-field-initializers, -Wno-unused-parameter,
-Wno-attributes and -Wno-long-long 
are supported by gcc-4.4
The way this test is made, it work for older gcc version than 4.4, so there is
no issue.

If new option should be conditionally disabled, that option should be added in
the NO_WARN variable.

I should say there is no much sense in the MAYBE_WARN vs NO_WARN variable
names.
Changing 
MAYBE_WARN to WARN_BEFORE_4_4
NO_WARN to WARN_FROM_4_4
may make sense.
