Lighttpd

When building lighttpd 1.4.41 (on Solaris sparc) with Solaris studio compiler it fails:

..
/bin/bash ../libtool --tag=CC --mode=link /ws/on12-tools/SUNWspro/solarisstudio12.4/bin/cc -m64 -xO4 -xtarget=ultra2 -xarch=sparcvis -xchip=ultra2 -Qoption cg -xregs=no%appl -W2,-xwrap_int -xmemalign=16s -mt -I/usr/include/openldap -lldap_r-2.4 -o test_configfile test_configfile.o buffer.o array.o data_string.o keyvalue.o log.o -L/usr/lib/sparcv9 -R/usr/lib/sparcv9 -lpcre -lresolv

Undefined first referenced
symbol in file
vector_realloc test_configfile.o
ld: fatal: symbol referencing errors

Please note that it succeed with gcc.

Following is info from Solaris Studio expert:

Two functions call each other:
vector_config_weak_push
vector_config_weak_reserve
But are otherwise uncalled.

One of them calls vector_realloc, which is undefined.

gcc is smart enough to remove the first two functions
because they are never called except from each other.
Therefore, the unresolved external is never manifested,
even though it's a bug in the code as written.

Because Studio cc generates the code, you see an
unresolved reference.

And here is possible fix:
