Hi, I'm trying to build NetBSD-current on OpenSolaris, well it fails:

#   compile  mkdctype/mkdctype.lo
gcc -O -DHOST_TOOL -I/opt/src/usr.bin/tn3270/tools/mkdctype/../../api -c -o
mkdctype.lo.o    /opt/src/usr.bin/tn327 0/tools/mkdctype/mkdctype.c
/opt/src/usr.bin/tn3270/tools/mkdctype/mkdctype.c:32:23: sys/cdefs.h: No such
file or directory *** [mkdctype.lo] Error code 1
1 error

nbmake: stopped in /opt/src/usr.bin/tn3270/tools/mkdctype
*** [dependall] Error code 2
1 error

Any ideas why this happens?
