E.g. the next stable release of Debian will likely ship with 2.3.1 .
So in this specific case fulfilling a 2.3.1 requirement would be easy,
while a 2.3.2 requirement would make it much harder to build gcc 4.4 .
Much harder ?
I don't think anybody who tries to build GCC from source will have any
problem building MPFR first.
They don't even need to do this, as mpfr can be built in-tree. It then
also won't interfere with a system-wide mpfr.

This is moot because for the reason given above, these hypothetical
regressions are restricted to gcc if the person building gcc is careful.
"careful" = uses an undocumented trick ?
Or where at http://gcc.gnu.org/install/ is this documented?
Hm, maybe it's not. I'm too lazy to search through all the
documentation of the GNU build system. While this may be written
someplace, it would certainly be a good thing to generalize the
paragraph about binutils in <http://gcc.gnu.org/install/download.html>.
Anyway, if you're afraid of regressions nothing prevents you from
building another mpfr out-of-tree (which is documented), and use that,
so the point is still moot. If you use a static library there is no
chance it will interfere with anything.
