The problem with ras.h is a bug in the IBM VAC C/C++ compiler, which was 
fixed in the update of june 2006. Please upgrade your compiler tot the 
latest patch release. More info on this problem (and the updates) can be 
found via the ibm website:


If the direct link doesn't work, just go to ibm.com, click on 'support 
and downloads', then in the box with title 'Support by product', click 
on the link 'software', on the next page click 'search' and then type 
'ras.h' in the box under '2. Enter search terms' and press enter. This 
will produce a list of problems related to ras.h. The first item in this 
list describes this problem: 'IY90668: SYS/RAS.H DOES NOT #IFDEF OUT 
"LONG LONG" TYPE FOR C89'. Click on this link and you will find info 
about compiler updates etc.

Let me know if it works (or not). Can you send a copy of your CONFIG 
file on the mailing ligts? We would like to compare it with the one we 
are using. It might be instructive.

best regards,
