No return type in math/lapack/pstrf.h

[Former user]

Hi,

Since PR #51 has been merged, I am not able to compile with gcc anymore:

/usr/include/blaze/math/lapack/pstrf.h: In function ‘blaze::blas_int_t blaze::pstrf(blaze::DenseMatrix<MT1, SO1>&, char, blaze::blas_int_t*, typename blaze::RemoveComplex<typename VT::ElementType>::type)’:
/usr/include/blaze/math/lapack/pstrf.h:151:7: error: return-statement with no value, in function returning ‘blaze::blas_int_t’ {aka ‘int’} [-fpermissive]
  151 |       return;
      |       ^~~~~~

‌

I think this is caused by the Wreturn-type flag for g++. Interestingly, it works when compiling with clang with the same arguments.
