Description

When compiling DCMTK on Solaris with SunPro Studio 12.6 in C++11, compilation fails with the following error message:

"ofstd/libsrc/ofcmdln.cc", line 1100: Error: nocreate is not a member of std::ios.
std::ios::nocreate is a proprietary extension that should indeed not be present in C++11 mode. However, we have a CMake test that checks whether ios::nocreate exists. Apparently this test is run with different compiler settings and determines that ios::nocreate is available.

Compilation with SunPro Studio 12.5 and 12.6 with C++ 11 and STL works now.
Closed by commits #407302562 (ios::nocreate problem) and #6911984f6 (follow-up issues).

It was a bug in CMake, not in DCMTK: https://cmake.org/pipermail/cmake-developers/2015-September/026584.html
For now we are using a workaround in the nightly builds, since the bug is only fixed in a CMake version that is not available on Solaris yet. Commit #6911984f6 had no effect, but will not be rolled back since it is a reasonable enhancement for DCMTK anyway.
