Are you using 'errno' in an unusual way in your code (check
your .o's to see which ones have __error() undefined)? Since it is
a macro expanding to '__error()', if you use it as other than an
"rval", you might have problems.
Just a side note, sys/errno.h has
extern int * __error(void);
#define errno (*__error())
Therefore, it is perfectly acceptable to use errno as an lvalue.
