Since it's public now, I might as well comment on it a bit ;-)
Generally I think it would be a good idea if LyX could be compiled
with gcc-2.7.2 since this seems to be some kind of de-facto standard.
The current development version does not compile, since gcc-2.7.2 does
not support a couple of features:
1. Name spaces (or at least std::) are broken. The only code that uses it
is the encoding stuff. It compiles quite well after a
perl -pi -e "s/std:://g"
in this dir. I don't have a clue if removing this breaks something (I
doubt it), but there should be a way using #defines do hide this from
gcc-2.7
2. The <algorithm> stuff used in DepTable does not work. I don't think
it is really necessary there anyway and a simple loop will probably
suffice.
3. Problems with operator declarations in wrap_string. There is a
constructor of a wrap_string out of " wrap_string<S>::value_type const *"
anyway, so the "offending" operators could be removed. This could mean
that an additional intermediate object is created but as I told JM
already I am fairly sure that this won't occur when using -O2.
4. --with-included-string probably has to be used when.
So I don't think it's too much effort to stay gcc-2.7 compatible.

PS: The patch is not to be considered as a "real patch to be included
in the source tree", but rather as a pointer to interesting places.
We probably need some kind of check for gcc-2.7 when running configure
but all this autoconf/automake stuff is clearly beyond me ...
