oh OK :-)

but if they are needed for bootstrapping they should be kept around, no?

I'm not very familiar with Autoconf and Automake (nor with
bootstrapping): is there a "compatibility table" around?  I quickly had
a look to the respective manuals but I was not able to find one.

OK old packages can always (almost) be time-machined back but if they
are needed for bootstrapping (for sexample if your work on GCC
bootstrapping is succesful) they should be in Guix proper, no?

is this a bug? :-)

Thanks for your work! Gio'
