I've included this patch in the gdb-11.22-1 test package.
I don't think this patch is upstreamable as is.

I guess I'd like something which stores both winpid and cygwin pid,
where the winpid is only used inside windows-nat with Win32 API calls, 
and the cygwin pid is the pid used by core code in POSIX API calls.

Unfortunately, writing that seems complex, as the 
CW_WINPID_TO_CYGWIN_PID mapping can't be done immediately after 
CreateProcess(), as some code in the inferior needs to run first (since 
to perform the mapping, it uses links created by 
pinfo::create_winpid_symlink(), called in crt0)
