[haiku-development] Build native gcc 4.1.2 for Haiku, but it's buggy.

Hi,
I guess the only way to make more applications or others running on Haiku
seemed like this, I must placing the codes to Haiku source tree then
create Jamfile, etc.
In order to avoid those things, I find a way to create
i586-pc-haiku-g++ can work
with autoconf, etc on Linux, then use it to build a native gcc for Haiku.
But when I compile applications on Haiku, I just notice that gcc 4.x
is buggy likes François said,
Sometimes, gcc print a message "received system's interrupt call" and
quit when compiling.
Second, I can't delete the files (except on Dano) after perl's
"./Configure -d" or "./configure.gnu" run.
I doubt the disk issue cause that, but nothing wrong to use "chkbfs
/Haiku" on Dano.
The procedures of that attached to this mail, hope the team could find
out what's the problem.
Thanks you for bringing Haiku to be a modern & powerful system.
A.L.
