Well, I didn't get any trouble compiling libsdl default branch. But
now I am confused because default branch is SDL 2.0, which is not
supposed to be compatible with SDL 1.3. Every library file in SDL 2.0
and the SDL include directory have a "2" appended to its name to avoid
name clashes with 1.x version. I got around this issue by creating
respective symbolic links.

But the real problem is that AFAIK ghost SDL is not supposed to work
with SDL 2.0, as it makes use of flags that have different names
between versions 1.3 and 2.0 and some functions which were removed
from 2.0 API. Here a list of errors I get:

But the curious part is that you are getting it to build with SDL 2.0
(SDL default branch)...
