Eventually, code will run on all machines anyway.

Take "Wine" for instance.

: Hello Xanax,
: 
: What are the results of the benchmarks you have made?
: 
: These routines are Windows based as well Yes?  I assuming this from the
: kernel32 and xCopyMemory references.
: 
: While no one likes inefficent code there are always trade offs.  For
: example (on a personal preference basis) code that works unmodified on
: different platforms and/or hardware is worth more to me because I consider
: porting it to other environments.
: 
: Always write for your target audience but bear in mind you may have just
: created a "smash hit" and everyone on all those "unfashionable types of
: computer" will want to run your software and, if so, you'll be glad you put
: the platform specific stuff into one Euphoria include file 
: 
: Rapidly prototype, robustly build for the future.
: 
: Here endeth the ramble.
