# Platform-specific targets. The ones ending in `-libc' are provided
# to enable comparison with the standard malloc implementation from
# the system's native C library.  The option USE_TSD_DATA_HACK is now
# the default for pthreads systems, as most (Irix 6, Solaris 2) seem
# to need it.  Try with USE_TSD_DATA_HACK undefined only if you're
# confident that your systems's thread specific data functions do not
# use malloc themselves.
