PHCpack package can't get version number

[DanGrayson]

An unfortunate consequence of adding the "-0" to the name of the executable recently:

$ phc -0 --version
-0 is not recognized.

, resulting in this example output:

$ git diff packages/PHCpack/examples/_version__Number.out
diff --git a/M2/Macaulay2/packages/PHCpack/examples/_version__Number.out b/M2/Macaulay2/packages/PHCpack/examples/_version__Number.out

 i3 : print v_1

And it's a bug in phc that the error is not indicated in the return code:

habanero$ phc -0 --version
-0 is not recognized.
habanero$ echo $?
0
