[Ecls-list] problem building ecl 0.9j for mingw + thread support

[lzenki at virgilio.it]

I get some problem building ecl version 0.9j for mingw32 + thread 
support.
No problem without thread support.

Please note, my mingw 
distribution has "native win32" thread support and
"pthread" support 
too (it is a port library from Red Hat).

Please help me !

Thank you 
all.
