This problem was also detected by Jim Kowalkowski at APS. A
changed cadef.h supporting the new C++ compilers will show up
in EPICS 3.12.2.
In the short term you can fix the problem by replacing all
instances of the field declaration "chid chid" found within
a structure declaration with "struct channel_in_use *chid".
There are only 3 lines that require changes. Function prototypes
do not require modification.
Note that this is only a problem for folks programming with the
more recent C++ compilers and is not a problem for ANSI/traditional
C programs.
