How did you configure eCos?
It was standard configuration. I have found that including
<cyg/error/errno.h> first and than <stdio.h> is causing problem.
a. there's no such thing as a "standard" eCos configuration. Do you
mean the default (template)? or what?
b. if you want to include stdio and friends, don't include the eCos
internal file (<cyg/error/errno.h>). If the code needs that file,
it will include it automatically.
A macro definition of errno in <cyg/error/errno.h> file
#ifdef CYGSEM_ERROR_PER_THREAD_ERRNO
# define errno (*cyg_error_get_errno_p()) /* Per-thread error status */
#else
extern Cyg_ErrNo errno; /* Global error status */
#endif /* ifdef CYGSEM_ERROR_PER_THREAD_ERRNO */
is inserted in a file name which needs to be included in <errno.h>
#if CYGINT_ISO_ERRNO
# include CYGBLD_ISO_ERRNO_HEADER
#endif
the CYGBLD_ISO_ERRNO_HEADER is <cyg/error/errno.h>. So errno is replaced
by (*cyg_error_get_errno_p()).
