this was because -v is a bailout-option ( as is -h )
it will do it's work and then exit ignoring anything
behind it on the command line
(this is common behavior for most command line tools)

so in 'php -v -q' the -q was never seen

but as -v and -h are only useful as interactive
options and for version checking in shell scripts
(including configure scripts), there was no sense
in putting out http-headers anyway, so i removed
it lately while fixing another issue
