[ECOS] Question CYGNUM_KERNEL_THREADS_DATA_MAX?

[Fredrik Hederstierna <fredrik at wespot dot com>]

I tried to change the cdl_option below and got a warning

 cdl_option CYGNUM_KERNEL_THREADS_DATA_MAX {
 display            "Number of words of per-thread data"
 flavor             data
 legal_values       4 to 65535
 default_value      65535
 description "..."
 }

In the code its used like this

// Set the data map bits for each free slot in the data array.
cyg_ucount32 Cyg_Thread::thread_data_map =
(~CYGNUM_KERNEL_THREADS_DATA_ALL) &

((1<<CYGNUM_KERNEL_THREADS_DATA_MAX)-1);


This shifts 1 << 65535, which looks strange to me... and GCC gives me a
warning.
 Is this code correct?
