These only happen on Win-Builder due to extra checks being enabled
there using the _R_CHECK_WALL_FORTRAN_=TRUE environment variable;
normally R CMD check ignores the warnings about COMPLEX*16 or DOUBLE
COMPLEX, including during CRAN submission checks. See, for example, a
recent upload of the 'QZ' package: the compiler warnings are present
[1], but the check status is OK [2].
WRE 1.6.5 expresses a weak preference for DOUBLE COMPLEX over
COMPLEX*16. If you're willing to make the old Fortran code closer to
Fortran 90 instead of Fortran 77 with extensions, replacing COMPLEX*16
with COMPLEX(KIND(0.0D0)) (and removing 10 spaces to the right to avoid
hitting the line length limit) seems to work too.
The C++ code at https://github.com/lafaye/IndependenceTests has a
couple of more serious problems:
* The 'new[]' allocation at src/cubature1.cpp:429 is freed using
'delete' instead of 'delete[]' at src/cubature1.cpp:462, which
crashes the process for me.
* The allocation at src/dependogram.cpp:635 seems to be leaked.
Hopefully the July 12 version of the package no longer contains them.
