Solaris 8 with forte cc compiler compile warnings

Im making static 64bit compilation of Apache and PHP on sparc Solaris 8 platform with native cc compiler. The binaries works just fine, but i get LOTS of following errors "main.c", line 1235: warning: argument #1 is incompatible with prototype: prototype: pointer to const unsigned char : "/output1/dev/out/php-4.0.6/ext/standard/base64.h", line 28 argument : pointer to const char "main.c", line 1235: warning: assignment type mismatch: pointer to char "=" pointer to unsigned char "php_ticks.c", line 56: warning: argument #2 is incompatible with prototype: prototype: pointer to void : "/output1/dev/out/php-4.0.6/Zend/zend_llist.h", line 53 argument : pointer to function(int) returning void "php_logos.c", line 87: warning: argument #1 is incompatible with prototype: prototype: pointer to const char : "/output1/dev/out/php-4.0.6/ext/standard/php_output.h", line 30 argument : pointer to unsigned char "session.c", line 477: warning: argument #2 is incompatible with prototype: prototype: pointer to const unsigned char : "/output1/dev/out/php-4.0.6/ext/standard/md5.h", line 58 argument : pointer to char "session.c", line 490: warning: argument #2 is incompatible with prototype: prototype: pointer to const unsigned char : "/output1/dev/out/php-4.0.6/ext/standard/md5.h", line 58 argument : pointer to char "base64.c", line 163: warning: argument #1 is incompatible with prototype: prototype: pointer to const unsigned char : "base64.c", line 34 argument : pointer to char "base64.c", line 165: warning: assignment type mismatch: pointer to char "=" pointer to unsigned char "base64.c", line 184: warning: argument #1 is incompatible with prototype: prototype: pointer to const unsigned char : "base64.c", line 71 argument : pointer to char "base64.c", line 186: warning: assignment type mismatch: pointer to char "=" pointer to unsigned char "crc32.c", line 110: warning: initializer does not fit or is out of range: -1 "dl.c", line 136: warning: improper pointer/integer combination: op "=" "html.c", line 111: warning: argument #1 is incompatible with prototype: prototype: pointer to unsigned char : "html.c", line 49 argument : pointer to char ETC....

ETC.... Im just wondering how worried i should be from these messages and what could be done to remove these errors!!!! My current CC looks like this: CC="/home/forte/SUNWspro/bin/cc -xarch=v9 -xCC" and configuration like this: cd ${APACHE_HOME} ./configure #------ CONFIGURE AND MAKE PHP ------------------------------------------------------ cd ${PHP_HOME} ./configure --without-mysql \ --with-apache=${APACHE_HOME} \ --prefix=${PHP_OUTPUT} make make install #------- CONFIGURE AND MAKE APACHE -------------------------------------------------- cd ${APACHE_HOME} ./configure --prefix=${APACHE_OUTPUT} \ --activate-module=src/modules/php4/libphp4.a make make install
