[1.7] "C:\cygwin\bin\git.exe: *** fatal error - could not load shell32, Win32 error 487"

[mikey]

I've seen this problem in cygwin 1.5 and it appeared to be related to 
the way that symlinks were implemented.  It became such a problem that 
I had to remove all my use of symlinks in my git repository at that 
time.  I switched to cygwin 1.7 and its symlinks seem to be much better 
behaved.

Since you're seeing the problem in 1.7, I'll speculate based on my best 
guess as to what this error message means.  In the 1.5 code, I saw this 
happen during cygwin's calls to NtCreateFile() when symlinks were being 
accessed.  I suspect that NtCreateFile() is simply making some DLL call 
to another library to do the work and that DLL somehow can't be mapped 
into cygwin's address space.  I tried remapping all the cygwin DLL 
addresses (I can't remember the command at the moment) but it didn't 
fix anything.  Maybe someone on the list can shed more light on whether 
my theory is correct and whether there's anything that can be done to 
fix it.
