Normally you don't have to do anything, just compile and install. the
"file" utility can be used to check this:

On some OS you will have to add some compiler flags, or possibly switch
to a different compiler. For example on my Solaris server:

> $ file plugins/check_dummy
> plugins/check_dummy:    ELF 32-bit MSB executable SPARC Version 1, dynamically linked, not stripped

Now if I run configure with "CFLAGS='-m64', I get this:

> $ file plugins/check_dummy
