Michael,
There is no any issues with cURL compilation or working on HP-UX 11.31 in
64bit, or 32bit modes. There is small error in configuration procedure. You
can reproduce it if setup environment variable CPP:
export CPP=/usr/ccs/lbin/cpp or it preprnt path /usr/ccs/lbin to PATH and
run configure. In this case configure will not detect C compiler properly:
"checking if compiler is HP-UX C... no"

If you unset CPP variable then configure write:
"checking if compiler is HP-UX C... yes"

This difference affects on configure detected CFLAGS if you did not pass it:
CFLAGS='' vs CFLAGS='-z +W 4227,4255 -s +O2'

Of course it is strange to use C preprocessor to detect is it native C
compiler or not but cURL do that for years. My patch works with native
HP-UX C preprocessor cpp as with C compiler in preprocessor mode.

Thanks
Dmitriy
