Subject: More docs on Intel ICC compiler, don't check for unistd.h any more as
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=75d93f235ce056f7fcc610fb50423c4583d170c5;p=dealii-svn.git

More docs on Intel ICC compiler, don't check for unistd.h any more as
gethostname must be in that file if it exists and the test failed with
ICC's preprocessor due to some unknown reason (file was there but cpp
failed to process the file properly).
