C function linkage and testing

Hi All,

This is my first posting to the list, so please be gentle.

;-)

I'm writing a number of C SQL-extension functions and it occurred to me 
that I might need to debug these things as some point. If I want to 
create my own main () function to exercise my extensions, what Postgres 
libraries do I need to link against?
For example, the VARSIZE and VARDATA macros are wrapped around internal 
functions; palloc and pfree also have dependencies.
If I want to use these calls within my extensions, and I want to run my 
extensions separately for debugging / validation purposes, what 
libraries should I link against?
Any help is welcome.
