[Bug c++/25238] New: Regression in compiling c++

[howarth at nitro dot med dot uc dot edu]

Regression in compiling c++. The file posRMSDPot.cc from the xplor-nih package
no longer compiles under g++ of gcc 4.1.0 but shows the compile error...

posRMSDPot.cc: In member function 'void PosRMSDPot::addRestraints(const
String&)':
posRMSDPot.cc:145: error: no match for 'operator>>' in 'iNoComments >> *
