 | Hi Joao,
 | 
 |  > Can these problems, specifically problem 4, be corrected?
 | 
 | You can fix this problem by including the following at line 31 of
 | octave-1.90/src/mappers.h:
 | 
 | #ifndef HAVE_ACOSH
 | double acosh (double);
 | #endif
 | #ifndef HAVE_ASINH
 | double asinh (double);
 | #endif
 | #ifndef HAVE_ATANH
 | double atanh (double);
 | #endif

 |   // Provide declarations for these whether they are actually missing or

 |   #ifndef HAVE_ACOSH
 |   extern double acosh (double);
