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

[Allan J Mui]

When I compile without libsigsegv enabled the build system works fine
but when I try to enable libsigsegv by setting the attribute
`HAVE_LIBSIGSEGV' to 1 (in config.h) I receive a compilation error as
follows: 
(MSYS shell output)...

I assume that building with libsigsegv is supported on mingw32. I am
using Windows XP SP3 and mingw32 (official version) gcc 4.5.2 . The
libsigsegv version is 2.9 (latest). When I ran the tests 277 tests
failed and I had to type "exit" in the window once while they were
running to continue.
