It is used in only 2 places in the postfix code:
work/postfix*/src/util/sys_defs.h
- The comment at the top of this file:
/*
* Specific platforms. Major release numbers differ for a good reason. So be
* a good girl, plan for the future, and at least include the major release
* number in the system type (for example, SUNOS5 or FREEBSD2). The system
* type is determined by the makedefs shell script in the top-level
* directory. Adding support for a new system type means updating the
* makedefs script, and adding a section below for the new system.
*/
/*
* 4.4BSD and close derivatives.
*/
#if defined(FREEBSD2) || defined(FREEBSD3) || defined(FREEBSD4) \
|| defined(FREEBSD5) || defined(FREEBSD6) \
|| defined(BSDI2) || defined(BSDI3) || defined(BSDI4) \
|| defined(OPENBSD2) || defined(OPENBSD3) || defined(OPENBSD4) \
|| defined(NETBSD1) || defined(NETBSD2) || defined(NETBSD3) \
|| defined(NETBSD4) \
|| defined(EKKOBSD1)
So basically there is no difference between FreeBSD5 and FreeBSD6, as
it is only used at this one location, and currently not used anywhere
else in the code.
work/postfix*/src/util/gccw.ref
- This file is used by the 'make gcctest' to compare the output of
building gccw.c to this file.
