bug#17157: [PATCH 1/5] Partially revert "dfa: improve port to freestanding DJGPP"

[Paolo Bonzini]

This partially reverts the following commits:
- df6da5d40a47abbc6e3451cb9fab7a8c9ede12cc.
- c40e7f7158109985b901ae67e5faa06160547471.
- 0995fc11214ebbb1c99a4b6d675fe615b0ed8539.

As far as grep is concerned, the #define *does* belong in gnulib.  gawk
can apply the fix in a common header file like grep's src/system.h.
