/*=============================================================================
*
*       The following wtbarr typedef is used in the fits_read_wcstab() routine,
*       which is intended for use with the WCSLIB library written by Mark
*       Calabretta, http://www.atnf.csiro.au/~mcalabre/index.html
*
*       In order to maintain WCSLIB and CFITSIO as independent libraries it
*       was not permissible for any CFITSIO library code to include WCSLIB
*       header files, or vice versa.  However, the CFITSIO function
*       fits_read_wcstab() accepts an array of structs defined by wcs.h within
*       WCSLIB.  The problem then was to define this struct within fitsio.h
*       without including wcs.h, especially noting that wcs.h will often (but
*       not always) be included together with fitsio.h in an applications
*       program that uses fits_read_wcstab().
*
*       Of the various possibilities, the solution adopted was for WCSLIB to
*       define "struct wtbarr" while fitsio.h defines "typedef wtbarr", a
*       untagged struct with identical members.  This allows both wcs.h and
*       fitsio.h to define a wtbarr data type without conflict by virtue of
*       the fact that structure tags and typedef names share different
*       namespaces in C. Therefore, declarations within WCSLIB look like
*
*          struct wtbarr *w;
*
*       while within CFITSIO they are simply
*
*          wtbarr *w;
*
*       but as suggested by the commonality of the names, these are really the
*       same aggregate data type.  However, in passing a (struct wtbarr *) to
*       fits_read_wcstab() a cast to (wtbarr *) is formally required.
