Hello Benoît,

In gambas/trunk/main/gbx/gbx_math.h, powl() is strangely declared with only 
ONE parameter (see line 65-67)  :
...
#ifndef HAVE_POWL
long double powl(long double x);
#endif
...

But in gbx_math.c, powl() is used with TWO parameters.
See line 137 in frexp10() :
...
  if (f == 0.0)
    l = x;
  else
    l = powl(10, l);
...

Regards,
Christian.
