Please note, that currently mingw\cygwin uses 'stabs' format for storing debug info by default, thus many (runtime) libraries has this information included. These formats shouldn't be mixed in one binary ('stabs' & 'DWARF'), otherwise binutils tools will be confused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31311 91177308-0d34-0410-b5e6-96231b3b80d8
