That check is there and looks correct.

Sent by private mail (it's rather large).

Currently we run SWIG at build time, but if SWIG's output is portable
(i.e. it doesn't depend on the OS it is being used on), and it doesn't
need any files which are part of the SWIG installation, we could ship
the generated sources so that users don't have to install SWIG.

Unfortunately the latter condition doesn't seem to hold as several
languages have a support library which is linked in using flags from:
"swig -<LANGUAGE> -ldflags" (this includes PHP4, although missing out
these flags doesn't seem to stop the PHP4 bindings from working).

I've also noticed "swig -python" has a "-modern" switch which generates
cleaner, leaner, faster code requiring Python 2.2 and up.  I'm working
up a patch to the build system to turn this on for appropriate Python
versions (although we could ship two versions if we switched to shipping
the generated code).

Cheers,
