pchar for v6 - problem

[Aljaz Tomaz RDSI]

Hi!
I have problem compiling pchar on Linux. I'm not a Linux expert so can
anyone help me. Here is an error:
c++ -g -O2 -I. -DSIZEOF_BOOL=1 -DSTDC_HEADERS=1 -DHAVE_UNISTD_H=1
-DHAVE_STRINGo
In file included from PctestIpv6Udp.h:40,
                 from main.cc:53:
