So I'd rather wait for 2.51, but for dumb stupid changes.

Of course it makes it hard!  Why don't you let the user configure
themselves?  That you run a modified Autoconf seems logical.  That you
preconfigure sounds wrong.

Yep, but merely introducing ac_test_f doesn't sound right either.  In
fact, it *is* on the list of things to change in Autoconf, but in a
cleaner way, which means much later.  There is something which works
today, that's all we need.

Hm, not a bad idea, now that we have ac_exeext available.  Alexandre,
Pavel, any comment?

Well, (i) check for foo, then (ii) foo$ac_exeext?
