Indeed, it has been correctly noted that the linker is crashing if trying
to use "--gc-sections". I was mistaken in implying otherwise. So yes, even
latest r3 has this issue.

The problem was that e3d.gpr didn't use "--gc-sections" in (default) "Debug"
setup. So it wasn't manifested unless using "-XBuild_Mode=Fast" (or Small).
So I wasn't doing that, wasn't even using his MAKE_XX.BAT (etc.) files,
just manually running gnatmake myself (without -Xblah=blah).
