[Rd] FYI: issue with arpa/inet.h on SunOS 5.9 (old gcc?)

This just information of my experience installing R on SunOS 5.9 today, not a request for help.
(in case anyone cares, and if not, I apologize for the distraction)

I am building R 2.6.0 (patched; svn revision 43319, 2007-11-01) and encountered the problem described below.

I believe the problem is an old gcc (version 3.0.4, built some 5 years ago), because the warnings do not occur when I specify

    CC = cc
in the environment before configuring, and building R succeeds.

Hence I'm mailing to r-devel instead of r-bugs, as suggested in the warning messages.

I don't have much information about the cc I used (I'm not the sysadmin of this or any Solaris machine), other than it resides in
/opt/SUNWspro, and appears to be part of "Sun Studio 11", whatever
that is.

The messages from R's configure were:

configure: WARNING: arpa/inet.h: present but cannot be compiled
configure: WARNING: arpa/inet.h:     check for missing prerequisite headers?
configure: WARNING: arpa/inet.h: see the Autoconf documentation
configure: WARNING: arpa/inet.h:     section "Present But Cannot Be Compiled"
configure: WARNING: arpa/inet.h: proceeding with the preprocessor's result
configure: WARNING: arpa/inet.h: in the future, the compiler will 
take precedence
configure: WARNING:     ## ----------------------------------- ##
configure: WARNING:     ## Report this to r-bugs_at_R-project.org ##
configure: WARNING:     ## ----------------------------------- ##

And then the same set of warnings for


At the very end configure reports:

configure: WARNING: could not determine type of socket length

Then, make fails with:
