dovecot - Feb 2009 - Compilation Issue on Old Boxes with macro in src/master/main.c

I'm throwing an error compiling with a custom-compiled gcc 3.2.3 on one box.

The configuration string is CC=/usr/local/gcc3.2.3/bin/gcc
CPPFLAGS=-I/usr/local/ssl/include LDFLAGS=-L/usr/local/ssl/lib ./configure
--with-ssl=openssl --with-ssldir=/usr/local/ssl/certs --with-pam --with-pop3d
--sysconfdir=/etc --localstatedir=/var

I've used this to compile on other older boxes with success.  And I compared
the command lines and they are identical.

This is the error I get with src/master/main.c

main.c:365:1: directives may not be used inside a macro argument
main.c:364:16: unterminated argument list invoking macro "printf"
main.c: In function `print_build_options':
main.c:372: syntax error before string constant

Changing the function to a simpler function without the ifdef's resolves the
issue and dovecot compiles.

I would really like to know why two boxes with the same compiler are failing on
one but not the other. Perhaps there's some program or library or
preprocessor or path or something out of whack.  Especially since using gcc 2.96
on the same box works!

However, I since this is a simple options output routine and (from my cursory
read) there may be some standards issue with this technique, I've also
patched the issue.

Thoughts?

printf is a macro in this system. I don't think that's normal (or even  
allowed by the standard?).
