Seems to be that, following R6RS’ lead, R7RS decided to come up with
new APIs that are close to, but slightly from, existing APIs. :-/

I wonder how these are specified. Does a *-kfreebsd-gnu build have
‘freebsd’? And ‘bsd’? Do *-gnu* have ‘linux’ defined, even when Linux
isn’t used? Does Cygwin have ‘unix’?
And above all: are people going to write #ifdef __linux__ish code when
what they mean is #ifdef __GLIBC__ or even something different?
Thanks,
Ludo’.
