Make hell of compilation in Linux enviroment (2)

Coming back again to make hell on my 486. Well, its insane to compile on this machine the first place. :D Last time.

So i am trying to compile icewm 1.0.9/1.2.37, bash 3.1 etc.
It takes time as usual in checking.

With icewm there is problem that it will not install to path i need, its hard coded. Cant disable nls with configure, it still builds it.

Testing again and again. I installed ccache, to speed up some repeating task, but it helps only so much.

Also annoying is to make diff files to fix compilations. Some program will not compile on gcc 3.4.6.
Some source is too old, some is to new. Some make scripts goes into loop etc.

Noticed in icewm that it makes some repeating task in source. Comparing path dirs, addin for themes etc.

So run (autoconf )autogen > configure > make > make install. Configure file itself is 500kb, source code with all the includes 1.5mb. Hm...

Well at-least icewm 1.2.37 its working instead my old 1.0.6 version :) When i log out then it closes all except X stays up. Also

icewm-session
icewm 

needs to be on xinitrc or nothing comes up except X cursor. Strange...
No need for that with icewm 1.0.9.

Is there a good reason for per source file executing compiler? When all parameters are same.
