[LAD] {OT} kind of some obscure c++-error

Hi everyone! This is not directly linux-audio, but still, I think here are some programmers, who know c++ quite well, bettern than me at least. I wrote some code, I can provide it if necessary and when I compiled it, I finally got this error(s), which I don't understand: In file included from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/ios:47, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/istream:44, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/fstream:44, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/ext/stdio_filebuf.h:39, from rm_midish_rl.cpp:13: /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/bits/localefwd.h :90:35: error: macro "isxdigit" passed 2 arguments, but takes just 1 In file included from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/bits/basic_ios.h:44, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/ios:50, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/istream:44, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/fstream:44, from /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/ 4.1.2/ext/stdio_filebuf.h:39, from rm_midish_rl.cpp:13: /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/bits/locale_face ts.h:4550:45: error: macro "isxdigit" passed 2 arguments, but takes just 1 /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/bits/localefwd.h :90: error: 'std::isxdigit' declared as an 'inline' variable /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/bits/localefwd.h :90: error: template declaration of 'bool std::isxdigit' /usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../include/c++/4.1.2/bits/locale_face I use g++-4.1.2 on debian etch stable. My code incorporates the following system-headers: iostream, fstream, string, vector, cstdio, cstdlib, cctype, csignal, unistd.h, ext/stdio_filebuf.h, errno.h and the readline headers. I'm not sure wether this is helpful info, but I can't imagine, where this comes from, I don't expect, that the system-libraries are that buggy. :-) Can anyone help me?
