Re: [bug-gawk] gawk 4.0.0 compile error when sigsegv is enabled (mingw32)

[arnold]

Hi.

This issue appeared for a while during gawk 4.0 development with cygwin,
but then the latest cygwin version (at least) of libsigsegv fixed it.
I'm not sure what's going on with mingw.

Eli - please submit a patch, either specific to mingw or renaming the
variable, as you like.

Libsigsegv has been more pain than gain for gawk, I have to admit.

Thanks,

Arnold
