Well no. The machinery that reads in Ada sources and performs the static
analysis is (often) included in the gcc suite and invokes the common gcc code
generation abilities.

It is not gcc itself, it is GNAT.

If one means gcc to mean the suite of language specific compilers using a
common code generation backend, then GNAT is a part of gcc.

If one means gcc to mean the C/C++ compiler only, then of course it is not the
same -- they compile different languages.

At any rate, it should come as no surprise that an Ada compiler is slower than
a C compiler -- an Ada compiler is doing far more work, plain and simple.
