DBI Installation

[CHENG XI]

While following the instruction below to instal DBI-1.15, I encountered a problem during the "make".  Here is the error message:

gcc -c -fno-strict-aliasing -I/usr/local/include -0     -DVERSION=\"1.15\"  -DXS_VERSION=\"1.15\"  -f PIC -I/usr/local/libperl5/5.6.0/sun4-solaris/CORE -Wall
-Wno-comment  -DDBI_NO_THREADS  Perl.c
cc1: Invalid option '-fno-strict-aliasing'
Perl.c:  In function 'XS_DBD_Perl_dr-discon_all_';
Perl.c: 32: warning: unused variable 'Perl___notused'
...

Does anyone know what the problem may be?  Is the C compiler problem?

Thanks in advance
