I may have just opened a real can of worms in my ignorance.

The reason I was trying out XDR is that I will soon have a need to 
exchange float and double data between FreeBSD, Solaris, VMS, AIX, and 
SGI. 

The code in src/lib/libc/xdr/xdr_float.c seems to use this approach (when 
IEEEFP is defined); treating float as two longs. The first test will be 
between FBSD and the Sun system I am hooked to.

I have no experience in VMS, AIX, or SGI. Isn't XDR a Sun protocol that 
wasn't picked up in the standards battles of the past few years. Or is it 
one that is generally accepted? Is there an RFC that covers this?
