Building gawk 3.7.1 on AIX 5.3

[Perry Smith]

I'm bumping in to a lot of problems building gawk on AIX 5.3.  I'm  
using gcc 4.3.1

The libtool adds in -D_XOPEN_SOURCE_EXTENDED=1 which changes AIX's  
includes files a lot.  fields like jmp_context become __jmp_context,  
gpr becomes _gpr.  And there are defines like MAP_ANON which are not  
defined at all.

I'm wondering a few things:  Does anyone know when / where the XOPEN  
flag was added?  Am I the first adventurer down the path of trying to  
get this version of gawk running on AIX?  Or, am I just missing  
something?
