It is impossible for me to use -I$(PREFIX)/include/posix so that I could si=
mply
#include <pthread.h> when using bfin-linux-uclibc-g++(!). The result whenev=
er I
just try to do something like #include <stdio.h> would be the following. It
does work when using gcc instead of g++ (but that's obviously no option for=
 C++
code)


a.c: #include <stdio.h>

bfin-linux-uclibc-g++ -D_GNU_SOURCE -D_REENTRANT -D__XENO__ \
     -I$PREFIX/usr/include -I$PREFIX/usr/include/posix -c a.c
