	When compiling something which uses statement expressions (e.g
	machine/endian.h to get at ntohl()), gcc complains that braces
	are not allowed by ANSI C.

	Below is a diff. for the relevant files.  Insert `__extension__'
	before the expression.

But this is arguably defeating pedantic.  Not only should your code
not use extensions, but the code that you're calling should not.  By
placing __extension__ in, you're allowing your code to use nonportable
code.

I agree with you that this sucks, because all you're really likely to
care about is the portability of YOUR code,  not the system code,
but I'm concerned about changing it.
