Changes between releases 3.00 and 3.11

Version 3.11

* libsharp C routines used for Spherical Harmonics Transforms and introduced in HEALPix 3.10 can now be compiled with any gcc version.

Version 3.10

* all Fortran facilities now support most of cfitsio's ``Extended File Name Syntax'' features, allowing the reading and processing of an arbitrary HDU and table column out of remote, compressed FITS files. For example, setting
infile = ftp://url/file.fits.gz[extn][col colname]
in anafast will download the FITS file file.fits.gz from url, uncompress it, open the HDU (extension) featuring keyword EXTNAME=extn, or the one with 1-based rank number extn, read the table column with TTYPE*=colname out of it and will analyze it.
It is also possible to perform a remote anafast analysis of a Planck Legacy Archive (PLA) sky map named map.fits via the PLA AIO Subsystem by simply setting infile=http://pla.esac.esa.int/pla/aio/product-action?MAP.MAP_ID=map.fits as input map file.
* yet faster synfast, anafast, smoothing thanks to libsharp routines1.
Note that some gcc versions (4.4.1 to 4.4.6) crash with an internal compiler error during compilation of libsharp. The problem has been fixed in gcc 4.4.7, 4.5.*, 4.6.*, 4.7.* and newer versions and was not present in versions 4.2.* and 4.3.*.
