Oh, absolutely.  But Autotools themselves are very unstable, so we've
apparently replaced spatial variation with longitudinal variation.
The Chicken project was undergoing too much churn trying to run correctly
with different installed versions of Autotools.  So we switched to CMake,
but that was even more unstable, and couldn't handle a bootstrapped
self-compiler well.

So finally we switched to the current scheme of Makefile fragments.
Each fragment specifies appropriate cc and ld options, including libraries
required, and then writes out a chicken-defaults.h file with a bunch of
HAVE_* macros.  That's all that's needed.

That you can cover for the plentiful and often gaping errors, misconstruals
and disinformation in your posts through sheer volume -- that is another
misconception.  --Mike to Peter
