Hello,

just one more question concerning the problem of loading dlls twice.
We installed cygwin into c:\Programme\cygwin
1) c:\programme is a symbolic link (like junction of sysinternal tools) 
to "c:\Program Files" via MKLINK /J 
and 
2) c:\Programme is a WINDOWS7 language German localized link/substition/ or 
whatever to "c:\Program Files" too.

Can this be a problem for cygwin too - concerning the problem of this thread?

best regards

Heiko
