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

Thanks for the fix to `builtin.c'; it works, but I encountered one more small 
problem when building in a cmd.com window:
(cmd.com window output follows:)...
mingw32-gcc-4.5.2 -c -O2 -gdwarf-2 -g3 -DGAWK -I.-Id:/sigsegv/include 
-DHAVE_CONFIG_H -save-temps  replace.c
In file included from replace.c:67:0:
missing_d/strftime.c:21:21: fatal error: config.h: No such file or directory
compilation terminated.
mingw32-make[1]: *** [replace.o] Error 1
mingw32-make[1]: Leaving directory `D:/gnu-source/gawk-4.0.0'
make: *** [mingw32] Error 2
...
I fixed this in the Makefile by adding "-I.." after "-I." in CFLAGS. When I try 
to type "make install" I use an MSYS shell because it has the
needed tools, especially `cat' already in the search path.
By the way, I already updated to libsigsegv 2.10. Here is how I configure 
inside an MSYS shell:
"./configure --build=i686-pc-mingw32 --prefix=<install-directory> --with-gnu-ld 
--disable-shared --enable-relocatable" . (Actually, I configure and build 
outside the source tree in another directory.)
