Subject: Sharing constants between C and Ruby code

Hello,

I'm new to ruby, but fairly experienced in C. I am using Ruby on Rails
to chat to a postgres database. I have some C functions that I can run
in the database backend. I would like to use constants defined in C
header files, e.g "#define MY_CONSTANT 100" within ruby code. I know I
can similarly define a constant in ruby, i.e. "MY_CONSTANT=100", but
given that I have quite a few of these, and synchronising the two files
could become tricky, is there some (preferably simple) clever way/hack
that I can define constants in a single file and use them both in C and
in Ruby?

Thanks,
Nat
