Hello Greg, thanks for answering.

If you want to take a look:

https://www.sm5bsz.com/linuxdsp/archive/lir05-02.zip


It is a very good SDR radio receiver program. It works in Linux and in 
Windows (MinGW) with several commercial radio receivers.

configure.ac:


AC_PREREQ(2.50)
AC_INIT(xmain.c)
AC_MSG_CHECKING([OS])
AC_CONFIG_FILES([Makefile])
AC_CONFIG_FILES([ft245.c])
BITS=`(getconf LONG_BIT)`

...

3630 lines of very long configure.ac script that uses $BITS variable 
several times to make some decisions.
...

Regards.

Ramiro.
