With so many planet-sized intellects working away at this I am a bit nervous about making yet another contribution of the style "how's this for weird?". But
On my system I have so contrived things that I have exactly one (yes promise and hope to die horribly) exactly one cygwin1.dll and there ain't nothing else at all, anywhere. Cygwin is not installed. The dll (latest issue 1.5.12 but not a snapshot) lives by itself with cygcheck.exe in a subdirectory. There is no mention of [cC]ygwin or [cC]ygnus anywhere in the registry. Moving to that subdirectory and typing cygcheck -s gives Warning: There are multiple cygwin1.dlls on your path in the output. Weirdly (?) the "Cygwin DLL version info" 1114k 2004/11/10 .\cygwin1.dll Cygwin DLL version info: DLL version: 1.5.12 DLL epoch: 19 DLL bad signal mask: 19005 DLL old termios: 5 DLL malloc env: 28 API major: 0 API minor: 116 Shared data: 4 DLL identifier: cygwin1 Mount registry: 2 Cygnus registry name: Cygnus Solutions Cygwin registry name: Cygwin Program options name: Program Options Cygwin mount registry name: mounts v2 Cygdrive flags: cygdrive flags Cygdrive prefix: cygdrive prefix Cygdrive default prefix: Build date: Wed Nov 10 08:34:47 EST 2004 Shared id: cygwin1S4 is provided *twice*, and then comes the Warning message.
