tested with gcc version 4.5.0 20091217 (experimental) (GCC)
perl v5.10.1 (this is weird . it complains .)
cannot remove path when cwd is /tmp/fbRcNjc7xj for /tmp/fbRcNjc7xj:  at
/usr/lib
/perl5/5.10/File/Temp.pm line 902

cygwin0.dll have __real__z* symbol...
it seems it should have been eliminated after linking...
well it seems that gcc compiler can't handle properly c++ symbols...
how to workaround this problem?? any suggestions are welcomed.

$ nm -s cygwin0.dll |grep -E "_Z(n|d)"
