Looking for Rake C code building examples with multiple plat



I’m currently using Rake to manage the building of a smallish
C library and associated C programs.

There’s some nice C building tutorials on Jim W.'s site
but I need to be able to build multiple versions of the library
(e.g. debug, optimized, instrumented) for multiple platforms
(e.g. Solaris/Sun C, Linux/GCC 4.x etc).

Has anyone used Rake in this way? I’d welcome any examples of
doing this in practice that anyone could share.
