Hi,

to reproduce this error, you can proceed like this:

Debian with
* linux-libc-dev-2.6.32-10 (/usr/include/asm/unistd_32.h defines
__NR_inotify_init1)
* libc6-dev-2.7-18lenny2 (/usr/include/sys/inotify.h does not declare
inotify_init1)

Run configure --target-list=i386-linux-user && make.

Regards,
Stefan
