unistd.h and fcntl.h are already used extensively on Solaris

Looks like they were stripped of the email. (And of the second attempt.)

By grepping I assume the splashscreen_config.h file is one place this 
was fixed for unistd.h. It is interesting to note that in some cases at 
least (eg splashscreen_sys.c) the C file includes <unistd.h> anyway.

We'll need to verify the changes for <sys/fcntl.h> in the 
genUnixConstants code. There tends to be a reason (often historical and 
possibly no longer applicable) for using the sys variants (though 
sometimes it was just that the non-sys version didn't exist at some 
point in time).

Cheers,
