So should the invokation of getloadavg() be moved to a separate C
module and then call the C function that calls getloadavg() from a
C++ module?

As a test I've included  AC_CHECK_FUNCS(getloadavg) between
AC_LANG_C and AC_LANG_CPLUSPLUS:

[...]
AC_LANG_C
AC_CHECK_FUNCS(getloadavg)
AC_LANG_CPLUSPLUS
[...]

On FreeBSD 5.2 with gcc 3.3.3 this
seems to work.
Is this a good idea or can one expect portability problems?
