[PATCH 2/3] t0027: Adapt check_warning() to MINGW

[PATCH 2/3] t0027: Adapt check_warning() to MINGW

[Torsten Bögershausen]

When running under MINGW, the native line ending is CRLF and not LF.
Adjust the check of the warnings with macros:
  WLC:  LF become CRLF on non-MINGW
  WCL:  CRLF become LF on non-MINGW
  WMIX: Mixed line endings: either CRLF->LF or LF->CRLF

Improve the information given by check_warning():
Use test_cmp to show which warning is missing (or should'n t be there)
