Hi all, Regarding this issue I had a problem about MinGW + MSys, with respect to Cygwin (actually that is the reason I joined the list) Environment: HP Compaq Laptop that logs onto a Windows Domain Scenario 1: (No network connection to the domain) -- MSys will take ages to start (around 15 seconds). -- If I start xemacs inside MSys it will start fast -- But executing any process (like compiling) within XEmacs yields = another 15 seconds -- Cygwin will behave as expected: No delays ... Scenario 2: (Network connection to the domain) -- Both Msys and Cygwin behave the same: All right Any clues ? Regards Daniel J. Rodr=EDguez -----Mensaje original----- De: min...@li...

ORBit2 is an implementation of CORBA 2.4 which is similar to DCOM and it's the only implemenation of C language mapping of CORBA, AFAIK.
