[mkgmap-dev] "Small" SRTM1 files and DEM maps

I use phyghtmap to build contour lines and also to download hgt data that I then use to build DEM maps with mkgmap. For a long time, SRTM1 files (and also VFP1) have all been ~24.7 MB in size, but lately (I don't remember since when) SRTM1 are also served as 12.4 MB files. phyghtmap is able to generate contour lines from those small files, as they seem to contain the same information but with a different compression ratio, but mkgmap fails to read them, and report them as missing. Would it be possible to get support for such files in mkgmap?
