I hadn't mentioned that but I had checked it, grep -i sua only found

Found the culprit meanwhile: /cygdrive/c/Windows/SUA/usr/lib was in my
PATH. If I remove it, the SUA man page is not displayed anymore.
So the more specific question: What makes cygwin 'man' check the PATH
(not the LD_LIBRARY_PATH) to find which library and - still - why does
that lead it to SUA man pages???
