Cross compilation

[KKO <kko%epia1.homeunix.net@localhost>]

Hi, all...
I'm trying to build my development environment for the hpcsh port on my
OpenBSD machine, but when I try building the cross-compiler toolchain
using

$ ./build.sh -m hpcsh -T /home/muyser/netbsd/cross -t

I get a
"/home/myuser/netbsd/src/tools/compat/../../lib/libc/gen/_err.c:21:
syntax error at end of input"

Has anybody seen this problem?
