Doesn't that tie us to GCC?  Certainly that is by far the most common 
compiler for the autoconf case, but we've had reports on list in the 
past from AIX and Solaris native compiler users.

You should turn this into an autoconf test.  See config/socket_nsl.m4. 
It shows how to conditionally figure out if certain compiler flags are 
needed.  Linker flags in that case, but the availability of -fPIC can be 
detected the same way.
