[Bug libgcj/28263] New: [win32] Memory Leak In Cleaning Exception Handling Contexts

["rmathew at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

There is a leak of 24 bytes of exception handling context per Java thread on
MinGW due to a hack that fools the MinGW runtime into thinking that
multi-threaded exception handling is in effect but avoids linking to the
correct __mingwthr_key_dtor() from mingwm10.dll and instead links to a dummy
version from libmingw32.a.

A workaround for avoiding this leak is to explicitly use -mthreads while
linking Java programmes with GCJ.
