# either the gcc floating-point software support (msoft-float libraries), or
# use the Motorola FPSP floating-point emulator in
# rtems/c/src/lib/libcpu/m68k/m68040/fpsp
# The default is to use the FPSP.
# To use the msoft-float libraries, uncomment the three lines below.
# You then should comment the M68KFPSPInstallExceptionHandlers() statement
# in rtems/c/src/lib/libbsp/m68k/mvme167/startup/bststart.c in bsp_start().
# Floating-point support will then be limited. See the mvme167 README file
