Trying to compile current on vax, I got stuck at:

#   compile  libiberty/argv.o
/usr/tools/bin/vax--netbsdelf-gcc -O2  -Werror    -DHAVE_CONFIG_H 
-I/usr/src/gnu/lib/libiberty -I/usr/src/gnu/dist/binutils/include

/usr/src/gnu/dist/toolchain/libiberty/argv.c -o argv.o.tmp
/usr/src/gnu/dist/toolchain/libiberty/argv.c: In function `buildargv':

/usr/src/gnu/dist/binutils/include/libiberty.h:54: prototype declaration

*** Failed target:  argv.o

argv.o.tmp
*** Error code 1

In argv.c, input is declared as: "char *input",
in libiberty.h it is declared as "const char *"

Could anybody fix this ?

thanks
