Use of STL iterators in GiNaC

Hi, I'm trying to compile ginac-1.5.1 with VC++ under Windows. I know "I should get myself a better compiler", but that being said, I've encountered runtime problems due to usage of STL iterators that might be wrong, essentially on std::vector. Problems I've noticed are: dereferencing end(), incrementing end(), decrementing begin()... I'm currently tracking down these issues by running the test suite in the source package, but this might not catch all of them. If you are interested, I can send a patch once I succeed to run the test suite completely. Bye, Michael.

Is CLN right, or is MSVC++ right? I don't think it is worth checking what the standard says about this. Even if it permits such sloppiness, they should be avoided. I'll prepare a patch for CLN. -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>

(Just for the record, I didn't find back this verbiage in GPLv3). Grand. I'll strip symbolic package from future octave binary releases. Michael.

This link will hopefully clarify this. If you still don't agree, there's no point in discussing the rest. http://www.gnu.org/licenses/gpl-faq.html#WindowsRuntimeAndGPL Michael.
