gcc ignoring defined macros?

Hi all,

This one is really wierd, and as neither Mark or I can figure it out,
maybe one of you knows what's going on!!

Some time ago, I noticed that non-debug builds of pgAdmin on Slackware,
did not pause to display the splash screen as they should. I spent about
2 minutes on the problem, and then moved on as I was busy with work
stuff, and promptly forgot about it.

Yesterday, Keith C. Perry posted a message to the support list stating
that under Slackware, the SSL combo box on frmConnect is empty, so he
was unable to select an SSL mode. First thing I checked was that I
really had built libpq on Snake with SSL support, which I had. I then
checked that pgAdmin was building with the SSL macro defined, which it
was. Finally I added a printf statement inside the #ifdef SSL block that
populates the combobox. That failed to print anything, indicating that
the preprocessor was not including that code.

So, I made a test program:

main() {
#ifdef SSL
printf("SSL defined.");
#else
printf("SSL not defined.");
#endif
}

This worked as expected when compiled with or without -DSSL on the g++
commmand line.

So I added some code to the top of pgAdmin3.cpp:

#ifdef SSL
printf("\nSSL is defined!\n\n");
#else
printf("\nSSL is not defined!\n\n");
#endif

and recompiled (see below). When running pgAdmin, it prints 'SSL is not
defined'. We're stumped here - any one else have any idea what's going
on?

Cheers, Dave
