That's a very bold assertion. ;-) Many upstream developers just copy&paste
their configure.ac scripts together from examples or other projects without
understanding them. The current maintainer might also not be the developer
who wrote the scripts (who is often the only one understanding them).
Case in point: There are bazillions of projects testing for the existence of
standard ANSI C89 / ISO C90 (not C99, C90!) functions (which have been
available on every even remotely modern OS for decades) in their configure
scripts, then just ignoring the results of the checks and just using memcpy
etc. without a second thought (which makes sense because those are part of
an ubiquitous, 23-year-old standard, but then checking for them in configure
and defining unused HAVE_MEMCPY etc. booleans does NOT make sense).
Likewise, projects routinely check for the existence of a Fortran compiler
without even including a single line of Fortran.
