tinyint

Hi all,
someone of you sent me an example of a new data type
called tinyint.

I seen that is using a well directory structure just
for compile a tinyint.c.

Is there any "empty" structure that I have to use in
order to delivery compile my email.c or I can
just use a single line command:

gcc email.c -I. -I /usr/include/pgsql/server ....

I seen also that a library called  libpgext.so
is created.

Shall I do the same ? Are guide line to use out there?
