If we're talking about size of binary archives then the change of total
size is less than 10%. Original sizes:

G7730B   ZIP     1 618 945  21.06.01  13:29 g7730b.zip
GCC30B   ZIP     2 305 071  21.06.01  13:29 gcc30b.zip
GPP30B   ZIP     2 414 441  21.06.01  13:29 gpp30b.zip
OBJC30B  ZIP     1 152 208  21.06.01  13:29 objc30b.zip
         4 file(s)      7 490 665 bytes

The same after stripping debug info from libraries

G7730B   ZIP     1 571 842  21.06.01  14:20 g7730b.zip
GCC30B   ZIP     2 235 735  21.06.01  14:20 gcc30b.zip
GPP30B   ZIP     2 267 709  21.06.01  14:21 gpp30b.zip
OBJC30B  ZIP     1 081 127  21.06.01  14:21 objc30b.zip
         4 file(s)      7 156 413 bytes

Of course decrease of size of libraries is more significant:

libgcc.a	         1555760          66976
libstdcxx.a     2002464          1285804
libsupcxx.a     211392          132006
libg2c.a          1423106         308500
libobjc.a          505686         188092
