[fpc-devel] (Re)compiling FPC or is there something like fpc.bpg?

[Adem]

  [Please bear with me while I am trying to formulate this question; it 
is a tough one to do succinctly]

If I am not mistaken, a version X of FPC is guaranteed to be compilable 
with version (X - 1).

If that is so, I am assuming, one would not have to 'make' version X; 
meaning you could compile version X with the binaries form (X -1) if you 
had something like fpc.bpg (i.e. project group).

The reason I am aiming for fpc.bpg is to avoid the problem of 'no spaces 
in file paths' problem.

Even though 'fpc.bpg' does not exist, it seems all the information 
necessary to genereate one is there in the numerous 'fpmake.pp' units in 
the 'source' directory.

Now the questions:

1) Does the 'fpmake.pp's contain all necessary information to generate a 
'fpc.bpg'?

2) If yes, would it be possible to use this newly generated 'fpc.bpg' to 
compile a new version of FPC without worrying about spaces in paths?
[I.e. does 'make' perform any 'deus ex machina' tricks that fpc.exe 
itself cannot?]

3) If yes, how much of the previous version's 'bin' folder would have to 
be there to compile 'fpc.bpg'?
[There are some 69 binaries under 'bin', totalling some 7.5 MB; I'd like 
to cut it down to a bare minimum if possible.]
