X-Git-Tag: release.4.9~5
X-Git-Url: http://djvu.git.sourceforge.net/git/gitweb.cgi?p=djvu%2Fdjview.git;a=commitdiff_plain;h=7d4802964b9e74506c63f43505b632f6e7b5db3c;hp=6389dcba572c6439acd226d27872c2f0db583875

removed swap (use qSwap instead).

Fixes Gentoo bug 401517, compilation problems with qt-4.8.
Unclear why is namespace std in scope at this point when using qt-4.8...
