RE: socket functions on HP-NonStop

[Joachim Schmitz]

Libfloss is not used (yet?), but has some hooks for this problem, the compiler 
wrapper script it contains uses -DSOCKLEN_T=socklen_t.

Other than that socklen_t is typedef'ed in <sys/socket.h> (and as an int) but, 
for some strange and probably historical reason, not used anywhere, in 
particular not in those socket funktions with use a size_t instead (which is 
typedefe'ed to an unsigned integer)

My 'fix' so far:

Is socklen_t already defined in the system or libfloss includes on this system?
Or does its definition come from gnulib (either from config.h or gnulib's 
sys/socket.h replacement)?
