I think the time has come to obsolete the IRIX 6.5 and Tru64 UNIX V5.1 ports: my test machines are falling apart one by one, bootstraps take between 24 (osf) and 36 (irix) hours, and both platform's EOSL is approaching:
* IRIX 6.5 until December 2013: http://www.sgi.com/support/services/irix_mips_support.html * Tru64 UNIX V5.1B until December 2012: http://tru64unix.compaq.com/tru64roadmap.pdf http://h30097.www3.hp.com/pdf/FINAL_Tru64UNIX_Policy_Page_24March2009.pdf http://h30097.www3.hp.com/external_letter_2010.pdf Given that there is not to be much user demand, this seems reasonable. I'm currently making a pass over the remaining testsuite failures and PRs to get 4.7 into as good shape as possible on both platforms. Tested by configuring without and with --enable-obsolete on alpha-dec-osf5.1b, installed on mainline. I will update gcc-4.7/changes.html with this change and the removal of -compat-bsd on Solaris soon.
