Subject: [Boost-commit] svn:boost r68554 - in trunk: boost/config/compiler boost/config/platform boost/config/stdlib boost/detail libs/config/doc libs/config/test
From: steven_at_[hidden]
Date: 2011-01-30 01:24:32

Author: steven_watanabe
Date: 2011-01-30 01:24:30 EST (Sun, 30 Jan 2011)
New Revision: 68554
URL: http://svn.boost.org/trac/boost/changeset/68554

Log:
Restore [66804], [66833], and [66834]. (fenv fixes.) I mistakenly reverted them in [68201] because [66804] was mislabeled.
Added:
   trunk/libs/config/test/boost_no_fenv_h.ipp
      - copied unchanged from r66804, /trunk/libs/config/test/boost_no_fenv_h.ipp
   trunk/libs/config/test/no_fenv_h_fail.cpp
      - copied unchanged from r66804, /trunk/libs/config/test/no_fenv_h_fail.cpp
   trunk/libs/config/test/no_fenv_h_pass.cpp
      - copied unchanged from r66804, /trunk/libs/config/test/no_fenv_h_pass.cpp
