* use these constants to construct the BASIC program loader (so it's now less cryptic what we're writing there)

3509d277d0 amiga: use -mtype vlink argument instead of -sc -sd when doing section gc. this prevents merging the bss section into the data section and is more compatible with pre-v2.0 OS versions. needs vlink 0.16b or newer
