in my copy of svn trunk libintl.h is found in main/hunspell/unxmacxi.pro/misc/build/hunspell-1.2.9/intlI heve no such file... strange.
There is a make target for libintl.h in the intl/Makefile When you go into the intl directory, run make clean then make you should have a libintl.h I think. Herbert
