Could you try the current cvs version(http://www.hylafax.org/cvs.php), i 
have got hylafax built with the cvs sourcetree on HP-UX 11.

That software was regular C, hylafax is C++...

...i think this problem is fixed in cvs.

Broken compiler - it has internal routines for memcmp(), memcpy() and 
memset() which use size_t and assume it is a certain type.  HP changed the 
definition of size_t between 10.20 and 11 to help with migration to 64 bits.

gcc 2.95 was only ported to 10.20 not 11.00 by cygnus i think, when the 
compiler is being built it needs to correctly determine size_t - but gcc 
-2.95 always ends up using 10.20 values.

...size_t is also needed for the C++ new operator, meaning your compiler is 
pretty much useless for most C++ programs :-(

For the above reasons  < gcc-2.95 will probably not work to well either on 
HP11, try downloading a precompiled/ported version of gcc-2.95 from the HP 
Users group:
         http://hpux.cs.utah.edu/

or download a cvs version of gcc2.96 from cygnus which have the problems fixed.
