It is a method of building a cross-toolchain in a let's say "short" way. It reduces the toolchain build time and is used by buildroot and other toolchain building systems. It works fine for most of the supported Linux architectures. It only fails for m68k, ia64 and tile. As ia64 and tile is not supported by Buildroot, I have'nt reported it, yet. > Regardless, I don't offhand see a need for unistd.h in that file. I'll > remove it during the next development cycle. Thank you very much, Waldemar
