If you´re using RHIDE, maybe can help you add the path of libstdcxx.

In Options->Directories->Libraries

add C:/djgpp/lib/gcc-lib/djgpp/3.1

(change according your DJGPP-path.

Maybe there is another better solution, but this is the only way that I
found to build c++ code whit RHIDE.

Don't  do it! Just add libm, i.e. add m in Options->Libraries, and check box
on left.

libm, because libstdcxx is linked automatically (if you don't disable
standard libraries).

Do you mean *patch*?

I'm not sure, but I see related problems discussed here.
