[Chicken-hackers] broken HEAD

[Felix]

Hello!


HEAD in "master" of the core system is currently broken ("make check"
fails). The reason is a bug in the macro-expansion mechanism that
lurked in there for quite a long time and for some weird reason
wasn't triggered until a totally unrelated change in the compiler
made it apparent. Fixing this is not completely trivial, so it may
take a few days.

(Thanks to Kon Lovett for reporting the problem and to Peter for giving
advice)


cheers,
felix
