Another reason is that - especially in gnulib - file names are often named
after a C function. When a source file provides a function named
'pagealign_alloc', it would be confusing to call the files that implement
it anything else then
modules/pagealign_alloc
lib/pagealign_alloc.h
lib/pagealign_alloc.c
m4/pagealign_alloc.m4

If there's a rename to do, I'm all for choosing self-descriptive names.
- getopt_int.h sound like it deals with options of type 'int'. A
better name would be getopt-internal.h.
- The getopt_.h naming does not make it clear that the file is preprocessed.
I would see it as an improvement to rename it to getopt.in.h or
something else that makes allusion to the getopt_.h -> getopt.h
substitution step.

Portability is not an argument for avoiding the underscore:
- Even the oldest platforms (DOS, Windows 3.1, VMS [1], SVR2) support
filenames with dashes and with underscores.
- The 'pathchk' program does not print warnings for filenames with
underscores.
Really, the issue is not about portability. It is about the personal
preference of a group of developers (the Emacs developers) to use dashes
instead of underscores.
