mico configure.in broken

[Bernhard Rosenkraenzer <bero linux net eu org>]

When trying to compile the mico package, part of the configure
(autogen.sh) output is:

checking for POSIXized ISC... no
expr: syntax error
./configure: test: : integer expression expected
checking for bison... bison -y
[...]
checking for main in -lncurses... no
[...]
checking for strdup... no
checking for strerror... no
checking for gethostname... no
[...]
checking size of unsigned char... 0

checking size of float... 0
checking size of double... 0


Check for ncurses by looking for main is a bad thing, because ncurses
compiled as a glibc add-on doesn't export a main function.

The malfunction in detecting strdup, strerror and all the sizes is related
to the configure script messing up the CFLAGS.

configure:1066: checking whether the C++ compiler (c++ -g0 -O2
-fomit-frame-pointer -mamdk6 -march=amdk6 -mcpu=amdk6 -pipe -s -s
-L/usr/local/lib) works

At this point, they're ok, what I specified in the CXXFLAGS variable with
"-s -L/usr/local/lib" added.

A few lines later, it's broken:
configure:1441: gcc -o conftest -O 0  -fomit-frame-pointer -mamdk6
-march=amdk6
-mcpu=amdk6 -pipe -s -fno-exceptions -I/usr/local/include -s
-L/usr/local/lib conftest.c -lfl   1>&5

Note the space between "-O" and "0" - gcc can't handle that...

The problem is caused by lines 165 and 166; the output of
echo $CXXFLAGS | sed -e 's/-g//g' -e 's/-O[0-9]*//g'
for me is 
"0  -fomit-frame-pointer -mamdk6 -march=amdk6 -mcpu=amdk6 -pipe -s"

Simply removing lines 164 to 176 does the trick.
