2767	#pragma warning pop is missing in boost/function/function_base.hpp	Denis Gurchenkov <dgurchenkov@…>	Douglas Gregor	"boost/function/function_base.hpp contains #pragma warning push directive but does not contain the corresponding #pragma warning pop.

As a result, global warnings state is changed and thus warnings in user code may not be reported correctly.

#pragma warnings push/pop are Visual C++ specific pragmas that maintain a stack of warnings state. Having push and no pop means stack nesting is broken.

Fix is trivial (patchfile is attached).
