It is not though. The full system is 8.5Mb in the preferred bzip2 format, and
C+g77 is 7.0Mb in source. I downloaded the lot in about 30mins to
my home machine.

ecgs release 1.1b reports:

toucan.stats# ./gcc -v
Using builtin specs.
gcc version egcs-2.91.57 19980901 (egcs-1.1 release)

so my guess is that this is the same release.
