I have no problem to patch Python to solve the issue,

If someone looking to the code can give me some hints,
I will appreciate
I am also not sure where the dlsym() is used in python.
At least, os.uname() works in python 3.8.7 and 2.7.18 in my
environment even without that snippet. It seems that os.uname()
does not use dlsym(). Do I overlook something?
This all started because Mark reported a problem building python 3.8.3:
https://cygwin.com/pipermail/cygwin-apps/2020-December/040765.html
https://cygwin.com/pipermail/cygwin-developers/2020-December/012019.html
It's strange that Marco never bumped into the problem.

I never built python using cygwin snapshots as Mark was trying to do,
all my builds were using 3.1.7.
Let me set a separate enviroment for building on latest snapshot
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
from cygwin1.dll
$ 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
I had concerns that I had somehow corrupted my build environment, and it was
Marco's successes that convinced me to reinstall 3.1.7 to recover a known-good
environment. Then seeing Marco go ahead and release the different Python releases
(yay!) I didn't investigate any further.
I'm now trying to locate the os.uname usage of dlopen/dlsym again just for the
record but am having some difficulty. I'll reply again when I've got it.
Thanks all,
..mark
