+Subject: [PATCH] make it compile with glibc-2.26 with an explicit cast to bool
+
+With glibc-2.26, openslam_gmapping failed to compile with:
+```
+| [...]/gridfastslam/gfsreader.cpp: In member function 'virtual void GMapping::GFSReader::RawOdometryRecord::read(std::istream&)':
+| [...]/gridfastslam/gfsreader.cpp:79:3: error: no match for 'operator==' (operand types are 'std::istream {aka std::basic_istream<char>}' and 'int')
+|    assert(is);
+|    ^
+```
+
+Hence, this commit explicitly casts to bool, so that the assert annotation compiles
+properly again.
