They required because I need sshd 64 bit exactly. This is Solaris, with
dual kernel, I can't mix 32 and 64 bit code in running executables due
to stability reasons. without -m64 code generates in 32 bit only mode.

* implementation.
*
* Furthermore, a strictly conforming program shall use only those features
* of the language and library specified in these standards. A conforming
* implementation shall accept any strictly conforming program.
*
* Based on these requirements, Sun's C compiler defines __STDC__ to 1 for
* strictly conforming environments and __STDC__ to 0 for environments that
* use ANSI C semantics but allow extensions to the C standard. For non-ANSI
* C semantics, Sun's C compiler does not define __STDC__.
*
* The GNU C project interpretation is that __STDC__ should always be defined
* to 1 for compilation modes that accept ANSI C syntax regardless of whether
* or not extensions to the C standard are used. Violations of conforming
* behavior are conditionally flagged as warnings via the use of the
* -pedantic option. In addition to defining __STDC__ to 1, the GNU C
* compiler also defines __STRICT_ANSI__ as a means of specifying strictly
* conforming environments using the -ansi or -std=<standard> options.
*
* In the absence of any other compiler options, Sun and GNU set the value

* gcc -traditional (K&R) undefined undefined
*
* The default compilation modes for Sun C compilers versus GNU C compilers
* results in a differing value for __STDC__ which results in a more
* restricted namespace when using Sun compilers. To allow both GNU and Sun
* interpretations to peacefully co-exist, we use the following Sun
