You made  a mistake  here as well !
It is supposed to be:

CC=/export/home/MySunstdio11/SUNWspro/bin/cc;export CC

CC  in CAPITALS.

That is why  configure finds /opt/csw/gcc3/bin/gcc   instead of   
/export/home/MySunstdio11/SUNWspro/bin/cc

LDFLAGS is    Link eDitor  FLAGS   that  gives parameters to ld(1)  

   read the  ld(1)   manual

# man ld

in  Solaris   the default  Library path is configured with  crle(1)

$ crle

Configuration file [version 4]: /var/ld/ld.config
  Default Library Path (ELF):   /lib:/usr/lib
  Trusted Directories (ELF):    /lib/secure:/usr/lib/secure  (system 
default)



When you need to link in libraries  not in you default library path
it is nessesary to tell ld(1)   where these libraries are.  hence:

LDFLAGS=" -L/usr/lib -L/usr/sfw/llib -L/usr/openwin/lib -L/usr/dt/lib"

(man ld )

 -L path

         Adds path to the library search directories. ld searches
         for  libraries first in any directories specified by the
         -L options and then in the  standard  directories.  This
         option  is  useful  only  if  the option precedes the -l
         options to which the -L option applies. The  environment
         variable  LD_LIBRARY_PATH  can be used to supplement the
         library search path. See LD_LIBRARY_PATH under  ENVIRON-
         MENT VARIABLES.
