Building Indy 9.0 with C++Builder5

Has anybody successfully built the Indy 9 components with
C++Builder 5.

When trying with C5Full.bat the dcc32.exe crashes
with a stack error (same with Indy 8 release).

When trying by building the bpk's within the ide
I get 9 unresolved external linker errors all
from modules IDSYSLOG.OBJ for objects
located in Idsyslogmessage namespace.
(Indy 8 could be successfully build this way)

I tried this on three different BCB5 installations
all with the same result (allways Professional version)

Did anybody see similar or have some suggestions
what could be wrong here ?

Thank you very much
