What's new in NXLib Version 1.1.2 compared to Version 1.1.1

TCP socket communication is speed up by setting TCP_NODELAY after
accept(). This socket option is not inherited!

The printed message concerning the exit status of the processes is now
directed to stderr instead of stdout.

Paragon's extended integer functions are now included.

On SunOS 4.1.x and IBM RS6K systems different f77 versions are now
supported. 

Check of environment variables in the partition file added.

Signals from incoming messages will be blocked during malloc() system
calls. If a programmer uses malloc() calls it is encouraged to include
the file nxmalloc.h which replaces malloc calls by corresponding calls
during which incoming messages are blocked. This was necessary
because NXLib uses malloc() within the signal handler for incoming
messages.

The internal NXLib functions to disable and enable incoming messages
are now based on a counter. This allows for nesting these calls
which is necessary to allow NXLib calls within hrecv() handlers.

The SIGIO handler is set up before the first socket is created and
SIGIOs are enabled. This didn't cause problems but it looks better
this way.

A bug which caused problems with isend() in conjunction with
setptype() is fixed.

mallopt() was called with only one argument. This bug is fixed.

Fortran stub for nx_initve was misspelled. This is fixed.
