The following comments are based solely on reading the message about
the port; I didn't try using EGCS yet.

Of these, why the first and the last needed to be renamed? Do they
clash with some other header files, which are not shown here?

Is there any reason not to put -remap into specs by default? Since
the specs file is now specific to the compiler and installs into a
compiler-specific directory, using -remap doesn't seem to interfere
with anything, right?

I would strongly suggest to fix that. Many people still use plain
DOS, even for development, and it isn't nice to prevent them from
rebuilding the compiler, especially since EGCS, as an experimental
version, will probably have more bugs to be corrected.
Are the LFN problems that hard to fix? What could possibly be so hard
to make them right there? Similar problems were handled in every
other DJGPP port, so I'd expect this one to be no harder.

I think this is a bad idea. Consider somebody who would want to add a
feature to the DJGPP port which is supported on other platforms, or
build a cross-compiler from this version: they *will* need some of the
``unneeded'' files, and it is a pain in the lower back to fetch the
full EGCS distribution (that might not be available by then, given the
speed they release new versions) and then merge the two distributions.
The cursing this will trigger will be heard from here to Latvia ;-).
It is okay to provide a smaller source distribution for those who
don't need the rest, but please at least let there be a separate zip
file with all the rest, at the same site, so those who need it could
have it.

Does the build process compile the compiler twice: once with an
existing gcc, and then again with itself? If not, maybe you should
suggest people to recompile the compiler after installing the initial
version, since the usual GCC build procedure actually does it in two
stages.
