I've done my best with this, including ripping out everything I had and 
replacing it anew. Perl scripts work, but C doesn't link. Ian (Collins) 
advises that the following is relevant:

At the outside, this is two weeks old. We've had something called a 
pineapple express flatten our fair metropolis, which is why I decided to 
deal with the C aspects of this, and perl is C just right under the 
hood. I like that about being a perl, because I know it's going to 
resolve to C at some point.

C:\Users\Fred\Documents>gcc deque.c
C:\Users\Fred\AppData\Local\Temp\ccEXIKGX.o:deque.c:(.text+0x8e): 
undefined reference to `DLAddBefore'
...
C:\Users\Fred\AppData\Local\Temp\ccEXIKGX.o:deque.c:(.text+0x63a): 
undefined reference to `DLDestroy'
C:/Strawberry/c/bin/../lib/gcc/x86_64-w64-mingw32/4.9.2/../../../../x86_64-w64-mingw32/lib/../lib/libmingw32.a(lib64_libmingw32_a-crt0_c.o):crt0_c.c:(.text.startup+0x25): 
undefined reference to `WinMain'
collect2.exe: error: ld returned 1 exit status

I'm frankly embarrassed by this. It was much easier to have MS's 
development tools whilst working on windows. Linking happens magically, 
with glitz and splendor. Cross-compilation is fraught.

BartC asks us whether we're programmers. I'm not, unless I have a C 
compiler that I can query through standard C, which, I assume 
heathfield's program is.

There will be a name collision on the word "library." Perl has this 
notion of a lib as a directory where files are found. In this 
implementation, it follows the -l notion.

Can someone tell me what this means?

CPPFLAGS= LDFLAGS='-pipe 
-L/opt/build/x86_64-492-posix-sjlj-rt_v402/mingw64/opt/lib 
-L/opt/build/prerequisites/x86_64-zlib-static/lib 
-L/opt/build/prerequisites/x86_64-w64-mingw32-static/lib '

 > Verify your perl import libraries.

Have I done so?
