nothing useful for a non-cygwin program?
$ cygcheck ./div.exe
C:\cygwin\home\Lee\t\div.exe
vs. built using cygwin:
$ gcc -fstack-protector-strong -o div.exe div.c
$ ./div
works
$ cygcheck ./div.exe
C:\cygwin\home\Lee\t\div.exe
C:\cygwin\bin\cygwin1.dll
C:\WINDOWS\system32\KERNEL32.dll
C:\WINDOWS\system32\ntdll.dll
C:\WINDOWS\system32\KERNELBASE.dll
C:\cygwin\bin\cygssp-0.dll
Was there ever a man page for cygcheck? I remember looking at one,
but maybe I it was https://cygwin.com/cygwin-ug-net/cygcheck.html ??
$ man cygcheck
No manual entry for cygcheck
$ info cygcheck
info: No menu item 'cygcheck' in node '(dir)Top'
