This problem comes from *executing libtool commands*
You can see in config.status of pango

$ cat config.status|grep postdeps
postdeps=''
postdeps_CXX='-lstdc++ -lmingwthrd -lmingw32 -lgcc_s -lgcc -lmoldname 
-lmingwex -lmsvcrt -ladvapi32 -lshell32 -luser32 -lkernel32 -lmingwthrd 
-lmingw32 -lgcc_s -lgcc -lmoldname -lmingwex -lmsvcrt'

rm ./libtool
./config.status #we can see *executing libtool commands*. and libtool is 
auto-generated.
and now resulting libtool has ill-tagged postdeps variable

$ cat libtool|grep postdeps
postdeps=""
       # don't eliminate duplications in $postdeps and $predeps
       libs="$predeps $libs $compiler_lib_search_path $postdeps"
       # $postdeps and mark them as special (i.e., whose duplicates are
         for pre_post_dep in $predeps $postdeps; do
               case " $predeps $postdeps " in
         case " $predeps $postdeps $compiler_lib_search_path " in
                   case " $predeps $postdeps " in
                     case " $predeps $postdeps " in
                 case " $predeps $postdeps " in
                 case " $predeps $postdeps " in
             for i in $predeps $postdeps ; do
postdeps="-lstdc++ -lmingwthrd -lmingw32 -lgcc_s -lgcc -lmoldname 
-lmingwex -lmsvcrt -ladvapi32 -lshell32 -luser32 -lkernel32 -lmingwthrd 
-lmingw32 -lgcc_s -lgcc -lmoldname -lmingwex -lmsvcrt"


Why we got postdeps instead of postdeps_CXX?

Regards.
