After running cygwin-setup and updating all cygwin-packages, perl no longer
seems to work (or maybe a coincidence).
Executing "perl" without any argument normally let perl wait for input from
stdin/keyboard.
But it immediately returns to the prompt (same behavior as 'echo ""').
I can do
perl
perl -v
perl -e 'print "Hello Perl\n"'
same result for all 3 of them (equal to 'echo ""').

That usually means a library is missing.
Try:
$ cygcheck /usr/bin/perl
C:\Cygwin\bin\perl.exe
C:\Cygwin\bin\cygperl5_40.dll
C:\Cygwin\bin\cygcrypt-2.dll
C:\Cygwin\bin\cygwin1.dll
C:\WINDOWS\system32\KERNEL32.dll
C:\WINDOWS\system32\ntdll.dll
C:\WINDOWS\system32\KERNELBASE.dll
C:\Cygwin\bin\cyggcc_s-seh-1.dll
or 'ldd /usr/bin/perl' and see if any library is marked as not found.
The problem could be a bad PATH, which finds another library of the same
name first, a deleted/not installed library (find dependencies with
'cygcheck -i --deps perl').
