Please could you install except.h libfuncs.h version.h in the plugin header directory? They're necessary for building dragonegg.
Created attachment 19415 [details] makefile patch
I've modified dragonegg so it only needs version.h and not except.h or libfuncs.h. When I implement exception handling support it will probably need except.h, but it is unlikely to ever need libfuncs.h.
I added version.h to the list of installed headers in commit 155692.
