Or simply running ./configure and report the error. Users trying to
compile GRASS are, according to the official documentation, advised to
run
./configure <optional custom options>
make
make install

I would like to see support for at least FreeBSD (BSD is the
predecessor of nearly all current operating systems), IBM AIX (a
commercial unix-based OS), and HP-UX (another commercial unix-based
OS). If we can adjust the G7 configure script to compile G7 on IBM AIX
and HP-UX, we would be to my knowledge the only GIS package available
for these high-performance operating systems, and I assume that we
want G7 to be available on commercial high-performance operating
systems.
