Since scalbnis only used in set_exponent, we could provide a fallback
implementation (I'm not a FP expert, but I'm not sure the libjava implementation
is very portable). What about the na�ve implementation:
double scalbn (double x, int n) { return x * pow(FLT_RADIX,n); }
Is FLT_RADIX available on Tru64 UNIX V4.0F and IRIX? That would at least allow
gfortran to build, even if we could enhance this code afterwards.
The fix is: add a check for scalbn in the configure.ac, add the fallback
function to c99_functions.c and the prototype to c99_protos.h. I can write that
and submit the patch for review if someone can test it on Tru64 UNIX and IRIX.
