[PATCH 1/2] system_data_types.7: Add 'fexcept_t'

[Alejandro Colomar <colomar.6.4.3@gmail.com>]

Note:  I used this commit to fix the comment that separates with gid_t.

It wasn't aligned with the rest (col 72).

Hi Michael,

Would you prefer a separate patch for the cosmetic change?
I put it in the same one, as it was in an adjacent line,
and the diff looks good; to avoid noise in the log.
But maybe a separate commit is better.

Thanks,

Alex
