Re: distinguishing octave versions with ifdef

[Xavier Delacour]

Please consider the following patch that adds a non-string/numerical
form of the octave api version in src/version.h.

This allows use of preprocessor conditionals to distinguish between
octave versions, and in particular is key for SWIG to be able to
generate bindings that compile under multiple versions of octave.

Thanks,
Xavier
