Thanks for testing. I've applied this patch:
2011-08-30 Bruno Haible <br...@clisp.org>
Avoid endless recursions if config.h includes some header files.
* lib/fopen.c (__need_FILE): Define already before including config.h.
* lib/freopen.c (__need_FILE): Likewise.
* lib/open.c (__need_system_fcntl_h): Likewise.
* lib/stat.c (__need_system_sys_stat_h): Likewise.
* lib/lstat.c (__need_system_sys_stat_h): Likewise.
