I can not replicate with latest snapshot
$ uname -svr
CYGWIN_NT-10.0-WOW 3.2.0s(0.340/5/3) 2021-03-01 15:42
nor in 64bit when building 3.8.8
For what I see the DLL is always using a proper import
$ objdump -x libpython3.8.dll |grep uname
2b9de0 2170 uname
2b9de8 2171 uname_x
the only thing not standard on my build system is a case sensitive
filesystem and mount
