!!!Caution for compiling with cfitsio library
{{category All of Data Analysis System(Servers and Terminals)}}
{{category Data analysis servers(anam* and anah*)}}
{{category Terminal Workstations(alws* and sbws*)}}
Compiling programs with cfitsio library may fail.
(Example) compress_fits
URL: http://heasarc.gsfc.nasa.gov/docs/software/fitsio/cexamples.html
=========
cc -I/usr/local/include -L/usr/local/lib -o compress_fits
compress_fits.c -lcfitsio -lm
/var/tmp/ccSFbWKg.o: In function `main':
compress_fits.c:(.text+0x489): undefined reference to `fits_comp_img'
collect2: ld returned 1 exit status
=========
This failure is caused by that the function "fits_compress_img" was not used since 27 April, 2011.
Instead of this, you can use the function "fits_img_compress" that has equivalent capability to "fits_compress_img".

This routine is obsolete and should not be used. The
ftools 'fimgzip' task used to call this routine (but that task has been deleted);
The name of the routine was changed 4/27/2011, to see if anyone complains.
If not, then this routine should be deleted from the source code.

This routine initializes the output table, copies all the keywords,
and loops through the input image, compressing the data and
writing the compressed tiles to the output table.
