What then? As far as I understand, it will work *only* if I have global reent
struct for each thread, and then I must switch _impure_ptr pointer in each
thead *manually*.

Probably I wasn't clear enough in my previous postings, sorry. It's not me,
it's an application that I want to port to Cygwin. Is it so unusual to have
*an application provided* errno variable (for every distinct thread)?
As I already mentioned, that approach works fine in Linux. As far as I know,
similar mechanisms are provided by FreeBSD (__error()), Solaris (___errno()),
UnixWare (__thr_errno()).
Is it true that Cygwin has no analogous functionality?
Anyway thanks for your help.
