Patch to avoid using "set -o pipefail" when not supported
My platform is: Developer Studio 2008 (MSVC 9), CMake generating NMake
makefiles, MKS 9.
MKS provides unix-like command line tools, though many provide only very basic
compatibility.
When CMake configures the tree, all the test scripts begin with "set -o
pipefail".
Unfortunately MKS bash doesn't understand the pipefail option:
D:\llvmtrunk\llvm\utils>which bash
c:/mks/mksnt/bash.exe
D:\llvmtrunk\llvm\utils>bash -c "set -o pipefail"
set: Unknown option "pipefail"
I'm attaching a patch to work around this limitation.
Tested on:
- LLVM trunk Windows + Cmake + MKS + NMake makefiles
- LLVM 2.8 Linux (with recent GNU batsh)
