[Starkit] 32 bit starkit on 64 bit Linux

[Detlef Groth]

Hello too,

may be tcl_platform(wordsize) (8-on 64bit machines and 4 on 32 bit machines) is a possible choice for getting the right library. Otherwizeit might be possible to try loading both versions of the library 64 and 32 bit and to catch the error for loading the wrong version.

regards,
Detlef
