Complex configure

[Leon Pollak]

Hello.

I have a library to be linked with my application. The library refers to a 
function which must be provided by an application.

This causes the "configure" process to fail at the phase "checking if C 
compiler can create executables" - linker fails without this function.

Can somebody among gurus recommend something "structural" to solve this in the 
most elegant way?

Thanks ahead.
