Comment:
That would be a bug in binutils, then; you should file a bug report on their
tracker.
On what basis have you chosen the values 129, and 132? Both are greater than
Windows' _sys_nerr limit, and will thus produce unacceptable results, if passed
to strerror(), or perror(). Consequently, I will not accept that, as a general
principle, these definitions may be arbitrarily adopted.
FWIW, the recommended work-around for this issue is, in the client code, after
including <errno.h>, to insert definitions such as
1. #ifndef ENOTSUP
2. #define ENOTSUP ENOSYS
3. #endif
4.
5. #ifndef EOVERFLOW
6. #define EOVERFLOW ERANGE
7. #endif

Ticket details:
I needed to include the following into errno.h to be able to build a recent
version of binutils:
1. /* necessary to build recent binutils: */
2.
3. #define ENOTSUP 129
4. #define EOVERFLOW 132
and suggest this may be done in general.
