Compiler warning(s)

[serkor1]

📚 What?

After PR #71 the compiler is complaining about unused variables in lookback-functions:

ta_WMA.c: In function ‘impl_ta_WMA_lookback’:
   ta_WMA.c:40:17: warning: unused variable ‘inReal_ptr’ [-Wunused-variable]
      40 |   const double *inReal_ptr = REAL(inReal);
         |                 ^~~~~~~~~~
   ta_WMA.c:37:7: warning: unused variable ‘n’ [-Wunused-variable]
      37 |   int n = LENGTH(inReal);
         |       ^

The general rule is this: Don't fight the compiler.

📋 TODO

Consider the following solution(s):

• Ignore the compiler.
• Fight the compiler.
• Construct a lookback-specific template and pass only relevant arguments to .Call() and ditch irrelevant one; without breaking the R function signature.

If memory serves me right, then compiler warnings should have made the CI/CD-runs fail for some compilers and OS (especially MacOS). But that was when R-CMD-check was used without r-universe.

Important

Going forward apply strict rules to the 'C'-side and make everything fail if there is warnings (regardless of its severity.)
