This is probably not enough. At least on Linux/x86_64 platforms the linker
also needs to be told about the 64-bit mode. The LDFLAGS variable is the
right variable for that. But sometimes $(CC) is used for linking without
$(LDFLAGS). So the complete recommended settings are:

  CPPFLAGS=3D"-m64"
  CC=3D"gcc -m64"
  LDFLAGS=3D"-m64"

Obviously intparam.h has been generated by a compiler in 32-bit mode.
Setting CC=3D"gcc -m64" should fix that.
