Quick question. I took a look at 'Installing Lazarus' [ 
http://wiki.lazarus.freepascal.org/Installing_Lazarus ] and all the 
examples for paths have no spaces in them.

Indeed, in my fpc.cfg, all paths are spaceless, such as 

There's also a special warning against them in the FAQ: "3. Check if the 
compiler *installation path has spaces* in it. *Make sure it doesn't!*" 
[ http://wiki.lazarus.freepascal.org/Lazarus_Faq#I_can.27t_compile_Lazarus ]

Is there a fundamental (still valid) reason for not being able to have 
it something like "c:\Program Files\Lazarus\fpc\2.4.3/units/$FPCTARGET/" 
at least under Windows?

It goes against everything we're accustomed to these days.

What would it take to remove that limitation, I wonder?

OK. I usually do my development under Windows and when I have to compile 
on Linux, I install Lazarus/FPC from a package and not worry about its

I am assuming this is optional. I.e., you can alson opt not to share a 
common source directory as well.

But, that would mean also altering how Lazarus behaves (under Windows at 
least). I doubt if I could get past the inertia.
Not knowing who to talk to is immensely discouraging.

My ideal installer would also be able to download only the sources and 
build them locally --instead of downloading a much bigger binary package.

I wonder if this would be possible. or even generally desirable.
