Comment (by ballapete):

 Actually it's this block in
 `jasper-3.0.6/src/libjasper/include/jasper/jas_types.h` that redefines
 `max_align_t`:

 {{{
   167   /*
   168   Assume that a compiler claiming to be compliant with C11 or a
 later version
   169   of the C standard provides a suitable definition of max_align_t.
   170   The JAS_NO_SET_MAX_ALIGN_T preprocessor symbol can be used to
 override
   171   this behavior.
   172   */
   173   #if defined(JAS_NO_SET_MAX_ALIGN_T)
   174           /*
   175           The user of this header is assuming responsibility for
 providing a
   176           suitable definition for max_align_t.
   177           */
   178   #elif defined(_MSC_VER)
   179           /*
   180           Define max_align_t as a preprocessor symbol since using
 typedef will
   181           cause problems.
   182           */
   183   #       define max_align_t long double
   184   #elif !(defined(__STDC_VERSION__) && (__STDC_VERSION__ - 0 >=
 201112L))
   185   #       define max_align_t long double
   186   #else
   187       typedef long double max_align_t;
   188   #endif
 }}}

 The patch adds lines #186 and #187 – which is too much! Or? (I'll test
 without that patch when `glib2` has built.)
