Linker errors and how to catch them

[Lubos Pintes]

Hi,
I just updated to DMD 2.062. I then tried to recompile somewhat bigger 
project. After fixing some errors, I received dozens of errors like this:
Error 42: Symbol Undefined _D3std6string6formatFYAya (immutable(char)[] 
std.string.format(, ...))
I didn't see them when compiled with DMD 2.060. I am using VisualD and I 
tried the "Rebuild solution" command to be sure everything is recompiled.
