[gdal-dev] Unable to set GDAL_merge NODATA or calculate statistics

I have two questions.
1. I have 32bit float rasters that I'm trying to merge. GDAL_merge does not seem to set the output nodata to the first input raster nodata value. There is a -n option, but the nodata value for a 32bit float is -3.4028235e+038. Entering in this value with -n does not set the nodata value in the output tif. Is there another way to express this value that gdal_merge understands?
2. Is there a way for gdal_merge to automatically calculate the statistics on the output tif? I have had issues with this before when writing out tif rasters with GDAL (c++).
