[Bug-gsl] mismatched declaration in wavelet/dwt.c (gsl 1.6)

[Steven G. Johnson]

Hi, I noticed a typo in gsl 1.6 that causes compilation to fail on AIX 
with xlc.  At the top, it declares:

static void dwt_step (const gsl_wavelet * w, double *a, size_t stride,
                      size_t n, int isign, gsl_wavelet_worksp\ace * work);

However, later on the "isign" parameter is declared as type 
gsl_wavelet_direction.  The fix is to change "int" to 
gsl_wavelet_direction in the top declaration.

Cordially,
Steven G. Johnson
