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.

 *
 * _STRICT_STDC         __STDC__ is specified by the C Standards and defined
 *                      by the compiler. For Sun compilers the value of
 *                      __STDC__ is either 1, 0, or not defined based on the

 *                      is limited to only those symbols defined by the C
 *                      Standard. _STRICT_STDC provides a more readable means
 *                      of identifying symbols defined by the standard, or in
 *                      the negative, symbols that are extensions to the C
 *                      Standard. See additional comments for GNU C differences.
 *
 * _STDC_C99            __STDC_VERSION__ is specified by the C standards and

 * ISO/IEC 9899:1990 and it's revision, ISO/IEC 9899:1999 specify the
 * following predefined macro name:
 *
 * __STDC__	The integer constant 1, intended to indicate a conforming
 *		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
 * of __STDC__ as follows when using the following options:
 *
 *				Value of __STDC__  __STRICT_ANSI__
 *
 * cc -Xa (default)			0	      undefined
 * cc -Xt (transitional)		0             undefined

 * gcc -ansi, -std={c89, c99,...)  	1              defined
 * 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
