[fpc-pascal]switch suboption usage

[Andy Sy]

fpc accepts -glc, but will it work?  Or does one need to do -gl -gc?

For the help screen, what does the <x> after the switch invocation
actually mean?  You have multiple -g, -a, -s and -i suboptions, but they
are not indicated as -g<x>, -a<x>, -s<x> and -i<x>.

Also, how does one figure out from the help screen when bunching together
suboptions (i.e. -CritoR) will work and when they won't?
