[Define to nothing if C supports flexible array members, and to
- 1 if it does not. That way, with a declaration like `struct s
+ 1 if it does not. That way, with a declaration like 'struct s
{ int n; double d@<:@FLEXIBLE_ARRAY_MEMBER@:>@; };', the struct hack
can be used with pre-C99 compilers.
When computing the size of such an object, don't use 'sizeof (struct s)'
Don't use 'offsetof (struct s, d@<:@0@:>@)', as this doesn't work with
MSVC and with C++ compilers.])
