[Bug testsuite/36284] New: gcc.dg-struct-layout fails AVR target - multiple reasons

[hutchinsonandy at aim dot com]

gcc/testsuite/gcc/gcc.dg-struct-layout-1 fails multiple times for AVR target
due to non-portable testcase.

This test has 28 generated variants, all fail.
Problems include:

1)Assumes int are 32 bit

gcc/gcc.dg-struct-layout-1//t001_test.h:119: error: width of 'a'

2) Assumes availability of DF mode
gcc.dg/compat/vector-defs.h:9: error: unable to emulate 'DF'

3) Some undefined problem - maybe size >32767?
short_enums30131.c:3: error: size of array 's' is negative


I will post snippet of log file to aid correction.
