yes, sorry

the gnulib code via the lib/idn-int.h.  for example:

bfin-linux-uclibc-gcc -DLOCALEDIR=\"/usr/local/share/locale\" -DHAVE_CONFIG_H 
-I. -I.. -I../../libidn-1.0/src  -I../../libidn-1.0/lib -I../lib 
-I../../libidn-1.0/gl -I../gl   -g -O2 -MT 
idn.o -MD -MP -MF .deps/idn.Tpo -c -o idn.o ../../libidn-1.0/src/idn.c
In file included from ../../libidn-1.0/lib/stringprep.h:32,
