OK, it seems that parts of gcc went used under Windows...
Maybe it will "easy" to port it native to Linux.

Since it is a All-In-On-Chip, there is not realy much hardware support
needed. Floppy, CF-Disks as external controlers, USB is On-Chip same
for LAN, serial, ...

"Self-Hosted" is "my" target since I have had MANY horrors with
cross-compiling

OK, I am on the LKM, but do you know a suitable "gcc" MAILINGLIST?
(I can not use NEWSGROUPS over GSM and since I can use E-Mail for
free using iMode... :-)) )
