Cygwin, Vista, and rcmd
Mon May 7 19:01:00 GMT 2007

I've been watching the groups, Google, and so forth with little luck to 
resolving the issue seen by myself and a few other people:

$ rlogin blah@blah
    9617 [main] rlogin 5392 e:\cygwin\bin\rlogin.exe: *** fatal error - 
couldn't dynamically determine load address for 'rcmd' (handle 
0x75E70000), Win32 error 127

So I finally did some research myself. I don't have a solution, but i have 
another name for the problem!

Error code 127 is the 'procedure not found' code in Win32. I searched 
through the code and the DLLs involved, and found that ultimately, rlogin 
is looking for 'rcmd' in mswsock.dll (linked through wsock32.dll). The 
'rcmd' export is clearly available in Windows 2000 and Windows XP (the two 
other versions I checked), and conspicuously absent in Vista. (Checked 
with depends.exe).

The only thing I could find on the development list was a note from July 
by Corinna Vinschen that there was work in progress towards replacing 
the winsock calls -- looks like we're going to need that for Vista.

I'm not looking for support, just sharing the results of my research in 
hopes of making the problem less mysterious. I guess not many people use 
this functionality (but I use it daily in my work! ;) )
