build error log

*Environment:
 - Gentoo kernel 3.17.8-gentoo-r1
 - Clang 3.5.0-r100
 - Qt5 dev branch from git source (not portage tree)

*How to reproduce:
 - Build konsole with qt5 dev branch ( with ./kdesrc-build --refresh-build konsole)

*Behavior to expected:
 - Build succeeded

*Behavior in fact:
 - Build failed with error " ProcessInfo.cpp:448:37: error: call to member function 'readLine' is ambiguous "

*Route cause:
 - As QtTextStream::readLine() has been overloaded in Qt5 dev branch[1] readLine(0) is detected as ambiguous.

*Suggestion to fix:
 - call readLine() without no arg to be set maxlen=0 as default. (see attached file)

sorry for typo.

*Root cause:
 - As QTextStream::readLine() has been overloaded in Qt5 dev branch[1]
readLine(0) is detected as ambiguous.

call readLine() without arg to be set maxlen=0 as default

Qt dev overloads readline()

call to member function 'readLine' is ambiguous

Thanks to Takahiro Hashimoto for report and fix
