Hi Uwe,

I'm not familiar with the Tru64-UNIX environment, but I'll see if I can
help.

Have you built bogofilter with Tru64-UNIX before?  What version of
bogofilter?

You are correct that the internal GSL code is being used.  The cc
error's filenames confirm that.

It sounds like a typedef or #define symbol may be changing after exp.h
is read (and the function prototype is given) and before exp.c is
compiled (where the function declaration appears). Have you tried
generating preprocessor output to see what the expanded prototype and
declaration _really_ are?
