If you say

  $ gnatmake -Pdmitry.gpr -XPlatform=x86_VxWorks

does it swap then? When we wrote our Project files we weren't aware of
Compiler_Command, in fact it may not even have been available, so we
have to name the compiler as well as setting the variables:

  $ i586-wrs-vxworks6-gnatmake -Pdmitry.gpr -XPlatform=x86_VxWorks

Of course, once the makefiles are set up it doesn't make a heap of
difference.
