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

   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 pathit 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.
