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

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.*.
