[Bug-tar] quick changes for MIPSpro C compilation

[James Bigler]

Hi,

Just downloaded 1.15.1 version to compile on my SGI IRIX system.  We 
don't install the GCC compilers, so I had to use the MIPSpro compiler 
version Comp7.3.1.3m.  I built a 32 bit build and it worked fine once I 
made a couple of changes to get it to compile.  I didn't actually try to 
change the compiler options to get it to compile it.  The manual code 
changes were simple enough.

% diff lib/argp-help.c~ lib/argp-help.c

<   struct pentry_state pest = { entry, stream, hhstate, 1, state };
---
>   struct pentry_state pest;
>
>   pest.entry = entry;
>   pest.stream = stream;
>   pest.hhstate = hhstate;
>   pest.first = 1;
>   pest.state = state;
% diff lib/argp-parse.c~ lib/argp-parse.c
