[bug-gawk] [PATCH] Fix portability for AIX.

[Michael Haubenwallner]

* inplace.c (_XOPEN_SOURCE): Define when not defined yet.
(_XOPEN_SOURCE_EXTENDED): Ditto. Needs to define a number.

_XOPEN_SOURCE_EXTENDED=1 may be defined via m4/arch.m4 already, thus the
conditional. And AIX headers break when not defined as a number.
