New Comment:
Do you understand that require_once/include_once does exactly the same
as these define checks you are using to prevent multiple exclusion?
In your particular example you are doing a conditional function
definition (since it is inside an if clause) which means the function
needs to be defined at runtime and cannot be added at compile-time.
This usually shouldn't matter, but you are trying to call the function
before you define it. In Funcs.inc you require DB.inc which calls
Bleh() and then after that require you define the Bleh() function.
This simply won't work, and it isn't a bug. If you are doing to do
conditional function definitions, you *must* define your functions
before you try to call them.
So yes, we understand perfectly what is going on. If you look at the
bug number for this bug, you might notice that this is number 33579.
That's a lot of "bugs". We really can't take the time to explain each
one like this. If we say something isn't a bug, 99.9% of the time, it
isn't. The occasional one slips through, of course, but in most cases,
including this one, it is simple user error that is better explained on
one of the many support lists.

It is obvious you have no idea what is going on and the reason they
need to be there.
I may from one page load one include instead of another. I'm not going
to use ugly stupid code when there are hundreds of files to update
merely to work around this bug.
There is a problem here and it is within the PHP engine. I'm sorry
that you do not wish to fix it.
I sincerely hope you people are more helpful to others.
Thanks anyway for not looking into the issue.

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system
is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
Try nuke those stupid define()'s and use require_once() instead..

Here's an update to the code, this reproduces the "Bug".
<?php // Test.php
require("Header.inc");
Bleh();
?>
<?php // Header.inc
require("Funcs.inc");
require("Emails.inc");
Bleh(); // Won't error
?>
<?php // Funcs.inc
if (!defined("_FUNCS_INC_")) {
define("_FUNCS_INC_", true);
require("DB.inc");
function Bleh() { printf("Blah\n"); }
} // _FUNCS_INC_
?>
<?php // Emails.inc
if (!defined("_EMAILS_INC_")) {
define("_EMAILS_INC_", true);
require("DB.inc");
} // _EMAILS_INC_
?>
<?php // DB.inc
if (!defined("_DB_INC_")) {
define("_DB_INC_", true);
require("Funcs.inc");
Bleh();
} // _DB_INC_
?>

http://wwwtest.amberalert911.net/debug.php
debug.php includes funcs.inc
funcs.inc includes emails.inc global.inc
emails.inc includes db.inc funcs.inc forms.inc MailServer.inc
db.inc includes funcs.inc global.inc
forms.inc includes db.inc
As you can see, it's not working as you defined. If this is not a bug
with PHP, perhaps it's a bug in Apache?
I was able to execute my example via the command line PHP, but not the
debug.php via the command line. Not sure what the difference really
is. The example is much simpler of course.
All of the listed files are quite large, no smaller than 200 lines each
so I'm not going to post them here, but look at the URI listed above.

Works just fine with all versions I can test right now (4.3, 4.4, 5.0,
5.1 etc.).
