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

[Prof Brian Ripley]

What OS was that compiler built for?  This happened when you had a 
version of gcc built for the wrong version of the OS, as gcc captures 
system headers.  (There's a warning about that in the R-admin manual.)

The 'report to' message is autogenerated by autoconf.

SunStudio 11 is a recent version of Sun's compilers, and much to be 
preferred to gcc 3.0.4 on that platform (and probably to any version of 
gcc there).
