 ==============================
 
 This is what ldd has to say about the
 linkage, and file about the whole:
 ==============================
 $ ldd hello.exe
         ntdll.dll
 => /cygdrive/c/Windows/SYSTEM32/ntdll.dll (0x77bd0000)
        
 kernel32.dll => /cygdrive/c/Windows/system32/kernel32.dll
 (0x77ab0000)
        
 KERNELBASE.dll =>
 /cygdrive/c/Windows/system32/KERNELBASE.dll
 (0x7fefda70000)
         cygwin1.dll
 => /usr/bin/cygwin1.dll (0x180040000)
 
 ==============================

For what it's worth, mine ("Enterprise") has a few more things.
Probably most are not needed add-ons for security, etc., but who knows.
Also, gdb run showed a few more Thread: lines; probably related.

        ntdll.dll => /cygdrive/c/WINDOWS/SYSTEM32/ntdll.dll (0x76f70000)
        kernel32.dll => /cygdrive/c/WINDOWS/system32/kernel32.dll (0x76e50000)
        KERNELBASE.dll => /cygdrive/c/WINDOWS/system32/KERNELBASE.dll (0x7fefcc90000)
        ADVAPI32.DLL => /cygdrive/c/WINDOWS/system32/ADVAPI32.DLL (0x7fefefa0000)
        msvcrt.dll => /cygdrive/c/WINDOWS/system32/msvcrt.dll (0x7fefe7e0000)
        sechost.dll => /cygdrive/c/WINDOWS/SYSTEM32/sechost.dll (0x7fefeea0000)
        RPCRT4.dll => /cygdrive/c/WINDOWS/system32/RPCRT4.dll (0x7fefd0c0000)
        SYSFER.DLL => /cygdrive/c/WINDOWS/System32/SYSFER.DLL (0x74950000)
        cygwin1.dll => /usr/bin/cygwin1.dll (0x180040000)

=====================================

-Wall (or -Wextra) "enables all the warnings..." (or even more warnings), 
according to "man gcc".
