OK, so if I add 'have_func("rb_block_proc")' to extconf.rb and:

#ifndef HAVE_RB_BLOCK_PROC
#define rb_block_proc rb_f_lambda
#endif

to the header file, I can globally replace rb_f_lambda by
rb_block_proc everywhere else and the result will build under 1.6.x ?

I don't have time to test this before I go to work but I will this
evening (unless someone points out some pitfall I've missed).

Sorry for the newbie questions but since I'm managing a public project
now I really want to do this the best way.

Thanks for your help,
