compiling kaffe 0.9.0 with glibc2

[3-417.3 Ales Pour]

Hello there,
while trying to compile kaffe-0.9.0 I got this error at the very 
beginning:
#error sizeof(int) or sizeof(long) must be 4
              long long      __int64 must be 8

In include/jtypes.h all SIZEOFs are 0.
What is necessary for me to do compile it on a glibc2 linux? 
(Well, I only assume it has something to do with glibc2 since I had 
no problem to compile kaffe before...)
Thank you.
