Hi,

testing with our 4.5-based compiler revealed that the new support for DWARF2 
EH isn't thread-safe when DLLs are involved.  Straightforward fix attached.

OK for mainline, 4.5 branch and 4.4 branch?


2010-06-27  Eric Botcazou  <ebotcazou@adacore.com>

	* config/i386/t-mingw32 (SHLIB_LC): Add -lmingwthrd.
	* config/i386/t-mingw-w32 (SHLIB_LC): Likewise.
	* config/i386/t-mingw-w64 (SHLIB_LC): Likewise.
