Two warnings at muParserTokenReader.cpp

Type of variable auto iEnd not equals the function return type int.

Line 372 in e70f957

auto iEnd = m_strFormula.find_first_not_of(a_szCharSet, a_iPos);

Line 395 in e70f957

    
           auto iEnd = m_strFormula.find_first_not_of(m_pParser->ValidOprtChars(), a_iPos);

So I guess to use the return static_cast<int>(iEnd) at

muparser/src/muParserTokenReader.cpp

Line 381 in e70f957

return iEnd;

and

muparser/src/muParserTokenReader.cpp

Line 403 in e70f957

return iEnd;

or

to use auto function return type deduction, i.e. auto ParserTokenReader::ExtractToken(const char_type* a_szCharSet, string_type& a_sTok, std::size_t a_iPos) const at

muparser/src/muParserTokenReader.cpp

Line 370 in e70f957

    
           int ParserTokenReader::ExtractToken(const char_type* a_szCharSet, string_type& a_sTok, std::size_t a_iPos) const

and auto ParserTokenReader::ExtractOperatorToken(string_type& a_sTok, std::size_t a_iPos) const at

muparser/src/muParserTokenReader.cpp

Line 392 in e70f957

    
           int ParserTokenReader::ExtractOperatorToken(string_type& a_sTok, std::size_t a_iPos) const
