Bugzilla Bug 24454

I wanted to emerge clanlib-0.6.5 as a dependency for the pingus game.
For some testing with it, I installed directfb earlier but removed the USEflag
for it. 
The clanlib-0.6.5 does not compile when it finds directfb installed, no matter
if I set the USE flag or not. There is a configure option for this, you can
switch on or off directfb. But on is the default. The ebuild uses `use_enable
directfb` to set the configure-option. But this doesn't work when on is the default!

If I manually add --disable-directfb, it compiles.

Reproducible: Always
Steps to Reproduce:
USE="directfb" emerge directfb
USE="-directfb" emerge clanlib
Actual Results:  
./configure of clanlib-0.6.5 checks for directfb which results in a compile error.

Expected Results:  
USE="-directfb" should give "--disable-directfb" to the configure-script and it
should not check for directfb itself.

what version of directfb ? 
 
could you post the error ? 

It's DirectFB version 0.9.18, the newest one in portage.
The error messages are as follows:

above that, everything seems fine.
Gcc version is 3.2.3, possibly a problem with the newer error handling in gcc3?

nope, simple fix ... the functions utilize unsigned integers while the directfb
prototypes are signed integers ...

i made a patch and ill update the ebuild in a bit

updated the patch in cvs ... should be all set now :)
