I wouldn't mind changing its name to AC_FUNC_MALLOC_GNU.  Could
you propose a complete patch along those lines?  Of course the old
name should be retained for backward-compatibility reasons, but
only the new name should be encouraged.

GNU/Linux 2.2, as well as several other platforms like MacOS X,
Solaris, etc.  However, Tru64 is definitely weirder than Debian so I
suppose it's nice to know about Compaq's web site.

Personally I've never used any of these "test drive" sites; too much
hassle.  I have enough trouble managing and using my own machines.

The Alpha has some really nice floating-point features.  If you want
to do interval arithmetic, for example, it's much nicer than the x86.

I long ago lost interest in porting to any machines that don't conform
to the IEEE-754 floating point standard (ISO/IEC 559:1989).  However,
if you're worried about floating-point portability to weird hosts, you
should definitely port to IBM mainframes, Crays, and the like, and you
should look into the ISO standard for porting to weird floating-point
machines (ISO/IEC 10967-1:1994).
