Certainly not, it is huge and rarely used.
E.g. on i?86-linux, linking all of libgcc.a objects except bid*.o into a
shared library is ~ 80KB .text, .5 KB .rodata, with the dfp stuff also in
it is ~ 900KB of .text, ~ 1.9 MB .rodata.  As libgcc_s is linked into a huge
number of apps, this would be certainly not acceptable.
