Thanks. I tried a few of those compiler switches without luck, so tried
to find the root of the problem. Looking at the code in the build
directory, i.e. the source file that actually gets compiled, I notice
that the function lc_statmap_ini IS indeed redeclared. In the source
(not build) directry, we have the lines in loopcontrol.c:

944 CCTK_FCALL
945 void
946 CCTK_FNAME (lc_statmap_init) (int * restrict const initialised,
947                               lc_statmap_t * restrict const lm,
948                               ONE_FORTSTRING_ARG)

in the build directory, we have instead

944 CCTK_FCALL
945 void
946 lc_statmap_init (int * restrict const initialised,
947                               lc_statmap_t * restrict const lm,
948                               ONE_FORTSTRING_ARG)

According to the manual, somewhere in the build process CCTK_FNAME was
supposed to alter the function name in order to declare another version
callable from FORTRAN. But instead the name was left intact. My next
question is thus where and when is FNAME defined, where in the build
process is it applied, and how.

Wolfgang.
