Any objections to the attached change?

I believe this will work in any POSIX shell.  The idea is instead of
processing all of the arguments and possibly blowing away quoting and
such, we process them one at a time and use shift and set to recreate
the argument list.

In my testing, this fixed the configuration problem I was having.

My configuration is:

CC="ccache gcc" \
CFLAGS="-O2 -march=i486 -mtune=i686 -D__USE_STRING_INLINES
-fomit-frame-pointer -pipe
-I/home/mhatle/build/host-tools/host-cross/include" \
CXX="ccache g++" \
CXXFLAGS="-O2 -march=i486 -mtune=i686 -D__USE_STRING_INLINES -fno-rtti
-fno-implicit-templates -pipe" \
CXXCPP="g++ -E" \
CPP="gcc -E" \
LD="ld" \
LDFLAGS="-s -L/home/mhatle/build/host-tools/host-cross/lib" \
AR="ar" \
AS="as" \
NM="nm" \
OBJCOPY="objcopy" \
OBJDUMP="objdump" \
RANLIB="ranlib" \
STRIP="strip" \
/home/mhatle/build/host-tools/build-tools/rpm5-20070629/configure \
--cache-file=wrs_config_cache \
--prefix=/home/mhatle/build/host-tools/host-cross \
--build=i686-pc-linux-gnu --disable-nls --without-python \
--without-perl --without-selinux \
--without-apidocs

This results in:
