Maybe you can help, Global variables?

[eluser]richfearless[/eluser]
I have a strange request, I deploy my applications on both Windows & Linux, and i have been confronted by an error in my code, across my site i use this method

Code:

<a href='&lt;?=base_url()?&gt;this/is/a/link'>blah</a>

to set links.

Now for some strange reason my AJAX goes wonkyup on Windows using ISAPI_REWRITE.
So i need turn off those pretty urls and add index.php to the end of <?=base_url()?> but for link-usage only, keeping images that use baseurl happy too

so what my question boils down to is, how do i setup a global variable similar to base_url() but with a different name & value.
