Absolutely, positively, 100%, NOT!

Error codes are an abomination, are impossible to keep consistent
between compiler implementations, and are against GNU coding standards.
The GNU standard is "filename:line[:column]: message".  Which is
why gcc never uses codes, even though dozens of other C compilers do.

n1k0 wants a way to disable certain warnings with a single number
that works across all compilers.  We can add that by translating
the "-fnowarn" code into our internal warning names while parsing
the command-line options.

However, in my opinion, warnings should never be ignored.  They
should be fixed.

Where, pray tell, in the ECMA standard does it specify the error
message format?  Or even the list of error codes that should be
emitted for various conditions?

If they are willing to do the work, then it doesn't hurt us.
Their license isn't GPL-compatible, but it is still technically
a free software license.
