The following bug has been logged online:

Bug reference: 2292
Logged by: Adriaan van Os
Email address: pgres (AT) microbizz (DOT) nl
PostgreSQL version: 8.1
Operating system: Mac OS X
Description: Calling conventions in docs
Details:

Section 32.9.5. Writing Code of the 8.1 docs says:

because other languages, such as C++, FORTRAN, or Pascal often do not follow
the same calling convention as C. That is, other languages do not pass
argument and return values between functions in the same way<<

This is nonsense. GNU Pascal and GNU C use the same calling conventions. In
fact, they share the same compiler-backend.

Sincerely,

Adriaan van Os

You seem to be assuming that Postgres will always be built using gcc. That
isn't the case.

Note that the manual says "this is usually difficult (when it is
possible at all)". I don't think there are much C compilers around with
calling conventions that a Pascal compiler cannot reproduce. Name me
one ! Anyway, recompiling with gcc will solve the problem.

The manual is simply taking an old prejudice as a fact.
