Just for Information: I had a strange problem with a small loadable extention
for Xorg server but only on 64-Bit system.
On 32-Bit Linux System the extention works fine, on 64-Bit system I got an error
"X Error of failed request: BadLength (poly request too large or internal Xlib
length error).
I have asked here in forum but nothing helps
Now I know what the problem was and hope, this solution will help somebody who
try to write a loadable extension too.

Simply the /usr/include/xorg/xorg-server.h was missed! That is a generated
header file and must be included at the first place in the extension AND NOT in
the client application / lib!
After including it the _XSERVER64 flag is set to 1 and everything allright!…
