I'm just dropping by to say that there are a few fasm source files that have bad line endings, at least for Unices: Some 0Dh,0Ah sequences should be replaced by 0Ah at the end of some message strings.

I don't know what Unices means, but FASM supports properly all variants: $0d; $0a; $0d0a and $0a0d, so the problem is not in FASM.

One presumes: 1 Unix, 2 Unices.

1 Matrix, 2 Matrices
1 Vertex, 2 Vertices
1 Dominatrix, 2 Dominatrices

Or in reverse:
2 Polices, 1 Polix

Unices=Unix-like OSes (e.g. Linux, FreeBSD, Solaris, etc.)

Although 0ah endings would be desirable for line sources to don't have troubles with some Unices text editors, it is not really mandatory. About the message strings, fixing that is a must, you should consider collecting all the instances you found and create a new thread in Compiler Internals.

Ah, sorry for my illiteracy...
