Cannot reproduce. No changes have been made to the ebuild since the bug was filed.

My build logs do NOT contain -flto, though no filter-lto was used... my guess is that newer ocaml versions are stripping this automatically because, presumably, ocaml knows it is incompatible with LTO.

This makes sense since the original errors looked like this:

ocamlc -safe-string -g -w -40  -custom -o omake_gen_parse.byte  unix.cma   omake_gen_parse.cmo
lto-wrapper: warning: using serial compilation of 5 LTRANS jobs
