Attached is some new one for libghemical. It fixes a small typo I made
and it checks for GL/gl.h. This defines HAVE_GL_GL_H, which could
replace HAVE_GL_H in src/typedef.h if you include libghemicalconfig2.h
(this patch is not attached, as it is simple).

dnl ... and this one is a small subset, maintained manually, which will be installed.
