Right.

While it's not the perfect 100% correct solution, it is practical -- very
few people will ever use flag_debug_asm, and those who do are exactly
the people who can (and will) figure out what's going wrong.

No, it's for a good reason.

Using "assert.h" like the old dwarfout/dwarf2out code is extremely bad.

Consider what happens on systems which have gcc already installed, but
no __eprintf in their existing libgcc.a -- they fail to build because
the dwarf code picks up gcc's assert.h, which references __eprintf,
which doesn't exist in libgcc.a.
