Hallo Kai!

 KR> That's the great freedom of choice of open source software.

Agreed.  However there is/was software that is part and parcel of every linux
distribution.  For me gcc is definetly one of those and has been since I first
used it on Solaris based machines (Sparc stations) in the real world way back
when no matter what their purpose was.  Also C and Unix did grow up together
way back in the late 60's when one wasn't possible without the other.  I still
believe that is true and there would be zero linux (bsd's too) distributions
without a C compiler and gcc was there at the beginning.

I have yet to see one of those in the real world, nevermind here where I am. 
Every Unixie machine I have ever encountered ALWAYS had a working gcc
enviroment since the late 1980's and continues to be true although I only have
access to the machines I currently am running.  There are differences between
the linux I originally ran back in the 1990's and today but gcc is still at the
heart of it all.

 KR> I see and understand why "your" systems need a dev environment
 KR> but that is not required for "any" existing system.

Understood.  I could easily replicate a non dev enviroment but I'd use gcc to
create it rather than rely on someone else's idea for such a crippled
machine(s).  Having said that I am not sure what I'd need from such a system. 
I am guessing it would sit in the corner collecting dust.

Bottomline is that LFS is an excellent document of how things fit together and
gcc is an integral part of that which makes it an excellent learning tool.

Het leven is goed,
Maurice
