Dear group, with "version don't know" (must have been 5.2 - 7.x) it worked to replace the delivered libgmp.so.version with a self-compiled and tuned own version. Usually this gave 5-8% speedup in some numeric functions. I tried with a newly generated gcc-4.6 and it failed though "make check" in gmp as in the dependent libs mpfr and mpc succeeded. Just typed this to prevent you from unnecessary effort. Peter P.S.: Nice you're again here, Steven. I've been (a bit) in sorrow.
