For information, built for ARM RISC OS (ie not a unix environment), 2.4.14
gives me a library file 724916 bytes long (no system-specific debugging
data included in the library); xmllint (which obviously only uses a subset of
the potential routines) builds to give 537784 byte executable.

Not equivilent to what I have then; building for PIC is more tricky with this
compiler.

Not really of interest to many, but as a comparison of code size may be of
use.

Since it was mentioned by someone else, and for comparison, expat for ARM
RISC OS compiles to an executable of slightly over 100k. I would expect the
scale of values to be typical for most architectures.
