[paragui-dev] Patch: fixing compilation problems

[Martin Bickel]

Hi,

here is a patch that fixes two compilation problems of the devel-1-1
branch with gcc 3.2.2 and its associated standard library:

In dblbuffer.cpp  the function isdigit() is located in <cctype>
And a string comparing against a NULL-pointer would result in undefined
behaviour if it compiled (it does not with gcc 3.2.2 ), as constructing
a std::string from a NULL-pointer is not allowed according to the C++
standard.


Regards,
Martin
