b) [The patch] allows any integer kind for the exit subroutine. This is in the spirit of Fortran 2003 which also allows any kind for most of the intrinsic procedures. Status quo is to give a link-time error that exit_i1 etc. does not exist.

For (b) there are several options:

i. Add i1, i2, and i16 versions to libgfortran ii. Convert kind > 8 to integer(8) and kind < 4 to integer(4) iii. As POSIX defines "exit(int)" and sizeof(int) is on most systems "4" convert everything to integer(4) iv. Convert everything to the default integer, i.e. integer(4) or integer(8) depending whether -fdefault-integer-8 is used.

I have chosen i

FLUSH implements (iii), see also PR30941.
