New issue 45 by kerdezixe: Cat's Eye renders as an empty circle (Ubuntu
9.10)
http://code.google.com/p/gnuxaos/issues/detail?id=45

On my linux (using latest svn, compiled without sffe) the cat's eye fractal
(with default option) render as an empty circle.

In formulas.c:
/* 2009-08-01 JB Langston
* On Mac OS X, for some reason Cat's Eye renders as an empty circle unless
* the bailout is slightly more than 4. This doesn't appear to happen on
any
* other operating systems, and it's not processor specific. It's probably
* a compiler bug, but I haven't been able to figure out exactly what's
* happening. I can work around it by subtracting LDBL_MIN from the amount
* before performing the bailout test.
*/
// #define LDBL_MIN 0.00000001

So i uncommented LDBL_MIN, and it render correctly.

# gcc -v
