[stunnel-users] connect error 0 running on ARM platform

Hello, Running stunnel 4.56 or 5.00 on an ARM platform (ARM926EJ) with Linux 2.6.36.4, I encounter the following error : the call to connect() return -1, but errno is set to 0 ! If stunnel is configured to use fork mode instead of pthread mode, the problem disapear. So it seems there is a problem, cross-compiling the program, with errno or __errno_location() in the program generated with pthread. I add the definition of _REENTRANT, without success ... (See $H1 at http://pauillac.inria.fr/~xleroy/linuxthreads/faq.html) Is somebody meet the same error ? Thanks for help. FWX.
