Comment (by ppelleti):

 I fixed the circular dependency for isSecureAccessEnabled, and got this
 order to work:

 {{{
   c-sources:           cbits/api/serial_transport_posix.c
                      , cbits/api/osdep_posix.c
                      , cbits/api/tmr_strerror.c
                      , cbits/api/tmr_utils.c
                      , cbits/api/tmr_param.c
                      , cbits/api/hex_bytes.c
                      , cbits/api/serial_reader_l3.c
                      , cbits/api/serial_reader.c
                      , cbits/api/tm_reader_async.c
                      , cbits/api/tm_reader.c
                      , cbits/glue/glue.c
 }}}

 However, the unpleasant part is that Cabal seems to always put the
 conditional c-sources after the unconditional c-sources, even if I put the
 conditional c-sources first in the Cabal file.  So, the only workaround
 seems to be to list all the sources twice: once for POSIX and once for
 Windows.
