I am having an issue with running the *gdalwarp* command from command prompt.
Basically I have a [raster WGS84 file][1], which I would like to reproject to spatial reference which is using the Azimuthal Equidistant projection, but with *"cubic"* resampling method.
This is the syntax that I am using:

    "C:/gdalwin32-1.4.1/bin/gdalwarp.exe" -s_srs EPSG:4326 -t_srs "+proj=aeqd +datum=WGS84 +lat_0=40.81266 +lon_0=14.414252" -r cubic -of GTiff "C:/vesuvius_wgs84.tif" "C:/vesuvius_cubic_aeqd.tif"

([40.81266, 14.414252][2] is the center of the raster)

For some reason when I press "Enter", the *vesuvius_cubic_aeqd.tif* file is not created, but instead I get the following text printed on my command prompt:

    gdalwarp [--help-general] [--formats]
        [-s_srs srs_def] [-t_srs srs_def] [-to "NAME=VALUE"]
        [-order n | -tps | -rpc | -geoloc] [-et err_threshold]
        [-refine_gcps tolerance [minimum_gcps]]
        [-te xmin ymin xmax ymax] [-te_srs srs_def]
        [-tr xres yres] [-tap] [-ts width height]
        [-ovr level|AUTO|AUTO-n|NONE] [-wo "NAME=VALUE"] [-ot Byte/Int16/...] [-wt Byte/Int16]
        [-srcnodata "value [value...]"] [-dstnodata "value [value...]"] -dstalpha
        [-r resampling_method] [-wm memory_in_mb] [-multi] [-q]
        [-cutline datasource] [-cl layer] [-cwhere expression]
        [-csql statement] [-cblend dist_in_pixels] [-crop_to_cutline]
        [-of format] [-co "NAME=VALUE"]* [-overwrite]
        [-nomd] [-cvmd meta_conflict_value] [-setci] [-oo NAME=VALUE]*
        [-doo NAME=VALUE]*
        srcfile* dstfile

What is the problem?

Interestingly, if I remove the *"-r cubic"* part like so:

    "C:/gdalwin32-1.4.1/bin/gdalwarp.exe" -s_srs EPSG:4326 -t_srs "+proj=aeqd +datum=WGS84 +lat_0=40.81266 +lon_0=14.414252" -of GTiff "C:/vesuvius_wgs84.tif" "C:/vesuvius_cubic_aeqd.tif"

everything works correctly, and *vesuvius_cubic_aeqd.tif* file is created.
To make it more strange, I tried replacing the *"-r cubic"* with *"-r bilinear"* or *"-r average"*, but again neither of these worked. I also tried, removing the *"-of GTiff"*, and that did not work either.

What am I doing wrong in the upper gdalwarp command syntax?

Thank you for the help in advance.
