Ah. Thanks for the info.

libc.1 you mean ? It didn't have that patch applied. Now it has. Thanks
for pointing this out. Turned out that the lib was okay, though. See
below.

Assuming that this alternative might be slower I looked closer and found
the reason: The bug mentioned in 1) appearantly involves the lack of an
extern "C" declaration. So the function name got mangled for C++ and
couldn't be resolved.

What I did now is to not include the header but insert the correct
declaration directly into the code. Ugly, I know. Is there any
pre-processor define that allows me to #ifdef code for specific versions
of HP-UX ? Couldn't find any (looking at stdsyms.h for example).

Thanks for your help,

Harri.
