Confirmed missing from cygwin.dll 3.3.0 64 and 32 bit and present up to 
at least 3.2.1. Also present in some other DLLs: 
cyg{asprintf,crypto,freetype,icons,iconv,lzma,ruby,ssl,unistring,usb,z}*.dll

Using SysInternals sigcheck and if you don't have that, base WMIC:

$ head /proc/version
CYGWIN_NT-10.0-19042 version 3.3.0-341.x86_64 (kbrown@moufang2) (gcc 
version 11.2.0 (GCC) ) 2021-09-24 22:07 UTC
$ sigcheck -a `cygpath -m /bin/cygwin1-old.dll`
