Would it be a bad idea to have 'libgnutls-config --cflags' return -I/usr/include/gnutls instead of -I/usr/include? If it did, no source changes would be required to support wmbiff. If gnutls-using apps are supposed to all change to '#include <gnutls/gnutls.h>' that's fine, I just want to make sure that the possibly better solution isn't going to come along in the next release. thanks, -neil
