Hello Nobu,

While I agree with the reasoning behind the flag, it will have serious
implications across many, many C extensions released on the wild
beyond Ruby bundled ones.

I had my share of experience fixing those incompatibilities in the
past on several extensions like Mongrel, RubyInline/ParseTree and many
others to compile against VC6.

The value of a warning will help the developers detect those, but if
we throw an error instead, will make the extension author life and our
day less happy than usual.

See the following gist:

Can we leave it as warning only? After all, if specific compilers fail
(due the similar VC limitation), authors will be able to spot the
issue due the warning.
