make cross -> as: unrecognized option `-mc68020'

[Chris Stich]

Hi,
thank you for your response. 
Some more questions ;-) :
Must the "normal" as in /bin support mc68xxx?
Because I built the m68k-rtems-as.exe in the
D:\cygwin\gcc-m68k-rtems\bin path.
And I understand, that the "make cross" takes than the as with the
"m68k-rtems-" prefix in this directory.
Maybe in one of the makefiles there is the prefix for the cross missing?
Am I wrong?

Kind regards, Chris
