compiling 0.74

[rsalz@osf.org]

For what it's worth; I compiled es.74 on OSF/1 reference implementation.
This is using GCC1.39 modified by OSF (Mike Meissner works here :-) and
the -ansi -pedantic flags.

Nice job!

I only had to comment out a few function declarations in stdenv.h:
	ioctl, memcpy, memset
I did this by adding -DOSF1 to the CFLAGS, and wrapping all three
declarations around
	#if !defined(OSF1)
	#endif

While I'm here, I'd like to recommend moving as much of those things
out of stdenv.h, in favor of (vendor-supplied) stdlib.h and unistd.h
