How to add gcc extension grammer support like __attribute__()

[hakureiR-eimu]

Meet with issue when parsing linux kernel source code that parse __aligned() as function
like
`
struct page {

}
/*

• The struct page can be forced to be double word aligned so that atomic ops
• on double words work. The SLUB allocator can make use of such a feature.
  */
  #ifdef CONFIG_HAVE_ALIGNED_STRUCT_PAGE
  __aligned(2 * sizeof(unsigned long))
  #endif
  ;
  `
