Hello,
In kernel\current\src\sched\mlqueue.cxx, several calls are made to
CYG_INSTRUMENT_MLQ().
In kernel\current\include\instrmnt.h, this call is either defined as
nothing or as an actual instrumentation instruction, based on the
setting of CYGDBG_KERNEL_INSTRUMENT_MLQ.
However, this setting can not be modified in ecos.ecc because the
cdl_option is missing in kernel\current\cdl\instrument.cdl
This patch fixes this:
