Hi, Struggling (again) with getting the ghemical stack compiled with gcc-4.0 for Debian, I suspect that libghemical seems to include g2c.h mostly because of the copy&pasted libmopac snippets in eng1_qm_mopac.cpp. Would it not make more sense to split these out into some publically installed header files in libmopac, which could then be included by libghemical?
