Building GCC is a complex process that involves building the compiler
multiple times as a sanity check on its correctness.
The stage1 compiler is built by the system compiler. The stage1
compiler is then used to build the stage2 compiler. The stage2 compiler
is then used to build the stage3 compiler. The stage2 and stage3
compilers are then compared -- any differences are an indication that
GCC was mis-compiled. This could be a bug in GCC itself, or a bug in
the stage1 compiler.
Additionally, you're building multiple languages. Assuming the
defaults, you'll be building C, C++, Objective-C, Fortran, Java and
associated runtimes for those languages.
And, believe it or not, each of the runtimes may need to be built twice
for 32bit and 64bit modes.
Needless to say, this takes considerable time.
