Manually setting macros in "macros.make" by-passes tests performed by the
configure script.  The script investigates its environment and saves
relevant information in several files.  One of these files is
libsrc/ncconfig.h, which contains things like the size of a C "int".
If the configure script is not executed in a 64-bit environment, then it
will not save that fact in its output configuration files.  The way to
set the environment for the configure script is by setting relevant
environment variables prior to executing the configure script and not
after by manually editing configuration files.

The bottom line is that, unless you know exactly what you are doing, it
is not a good idea to by-pass the configure script by manually editing
output configuration files such as "macros.make".

Please repeat my previous instructions.  When they call for setting
environment variables, please do just that -- and only that -- and do
not subsequently edit any configuration files.

Please let me know if this helps.
