thanks for checking.

unsure.  there are, now, two problems.  on the nesting issue + error - I read
(but forgot to take notes) that Debian maintainers do not use the '-ffast-math'
flag, so wonder whether it's an optimisation thing.  second prob - I only have a
Debian VM, pre-installed on the Chromebook, v 3.7.0.8 compiled by Andreas B.
that does not like the .inc, parse errors when it hits the '#ifndef (global...)'
etc; which changes did you (have to) make to the file(s), other than version
change?


regards, jr.
