[Gm2] INTEGER8 array element conversion error

[SiTex Graphics]

Hi Gaius,

Thanks for taking a look at the INTEGER8 indexing problem.  I've
stumbled across another bug with INTEGER8 vars.  If an array element
of type INTEGER8 is returned from a function with a different return
type (INTEGER32 in this case), gm2 performs an incorrect conversion.
Test files attached.  Compile with:

gm2 -o test8 -fiso -fmakeall test8.mod

Returning a simple variable of type INTEGER8 seems to work fine.  XDS
and Stonybrook both automatically handle the conversion.

Thanks,
Scott
