As one data point, I just built and installed Postfix with "new"
dtags on a pretty-old test VM that has no prior Postfix shared
libraries. This VM is reset after each use.
Linux c4eb.porcupine.org 2.4.21-27.0.4.EL #1 Sat Apr 16 19:00:33
EDT 2005 i686 i686 i386 GNU/Linux
Both the build and installation completed without error.
To demonstrate that this system supports the "new" dtags:
$ readelf -d bin/sendmail
Dynamic segment at offset 0x42a4 contains 28 entries:
Tag Type Name/Value
0x00000001 (NEEDED) Shared library: [libpostfix-global.so]
...
0x0000000f (RPATH) Library rpath: [/tmp/usr/libexec/postfix]
0x0000001d (RUNPATH) Library runpath: [/tmp/usr/libexec/postfix]
...
Conclusion: the odds that "new" dtags will break the build are
becoming astronomically-small.
(Side note: this show the silliness of using "new" in a feature
name. After 10 years or so it can hardly be called new.)
