[Groff] Re: [Mingw-users] Problems Building "GROFF" with MinGW

[MARSHALL Keith]

Earlier, I asked how I might work around this problem ...

This advice led me to extend my patch for "strerror.c" ...

thanks Earnie.

Short answer here is "I don't know -- probably just the same error".
I didn't actually try this, since Earnie's reply had already led me
to a working patch.

Greg also asked ...

In this case, I don't think either is relevant -- GROFF is a GNU package
so I just followed the conventional GNU build sequence for UNIX ...

        ./configure
        make

This wouldn't be expected to build any groff.dll -- just a statically 
linked
libgroff.a !

Thanks for your help, guys.  I have now got a lot further with the build,
but tripped up again with ...

I haven't really looked into this yet, but I already know how to fix the
"mkdir" problem, and I expect to find the "fork" and "wait" will be
coupled with an "exec...", which I can replace with the corresponding
"spawn..." -- do I need to #include <process.h>, as I used to with MSC-6?

Any tips on implementing an equivalent of the "pipe" function, or will 
this
depend on how "do_html" is using it?
