--- Comment #14 from Martin Sebor <msebor at gcc dot gnu.org> ---
I would suggest to keep the warning simple and avoid overdesigning it with
workarounds for this case. The solution in comment #12 (copied below) seems
like a good approach for avoiding the duplication and the warning. It's
already commonly used to deal with non-standard implementation-specific macros
that portable programs cannot otherwise rely on.
1149 if ( cchRead < 0
1150 && ( errno == EAGAIN
1151 #if EAGAIN != EWOULDBLOCK
1152 || errno == EWOULDBLOCK
1153 #endif
1154 ))
