Comment (by kgardas):

 Not at all! GCC by default generates 32bit code:

 {{{
 karel at silence:/tmp$ cat hello.c

 int
 main()
 {
 return 0;
 }

 karel at silence:/tmp$ gcc -o hello hello.c
 karel at silence:/tmp$ file hello
 hello: ELF 32-bit LSB executable 80386 Version 1 [FPU], dynamically
 linked, not stripped, no debugging information available
 karel at silence:/tmp$
 }}}

 In addition this define is not defined by default, but when you use -m64
 option. Then it's used. BTW: I'm also a little bit confused by the fact
 that when I invoke config.guess from the command-line it claims it's
 running on i386-pc-solaris, but if I run ./configure then it shows x86_64
 -unknown-solaris...
