Got warnings while installing Apache2.2.8

[Vivek Thite-Patil <vivek.thitepatil@xxxxxxxxx>]

Hi ,

 When I installed "Apache2.2.8", I used the following commands.

CC="/opt/solstudio12.2/bin/cc"

CFLAGS="-xtarget=generic -m64 -xO4"

CXX="CC"

CXXFLAGS="-xtarget=generic -m64 -xO4 "
LDFLAGS="-L/usr/lib/64 -R/usr/lib/64"

./configure
--prefix=/opt/apache2 --enable-so --enable-mods-shared=most --with-included-apr
--enable-lib64 --enable-rule=INET6 --libdir=/opt/lib64
-with-iconv-dir=/opt/lib64 --with-expat=builtin 

  make 

 make  install

       But I got the below warnings at the time of the Apache2.2.8 installation -

Could you please let me know why these warnings are there?

Is it a complete or incomplete installation?

Thanks in advance.
