[Bug-cpio] MinGW build bugs w/ cpio 2.11

[Michael Cronenworth]

Hello,

I'm running Fedora 14 x86_64 and attempted to build cpio 2.11 using the 
Fedora MinGW environment. Unfortunately the build did not go smoothly.

Configure line:
CC=i686-pc-mingw32-gcc ./configure --build=i686-pc-mingw32

Bugs:
1. lstat() and stat() defined in filetypes.h
2. readlink() used in src/copyout.c, MinGW has no equivalent.
3. gethostbyname() used in lib/rtapelib.c without winsock2.h present. 
This causes a compile error in that the correct, MinGW gethostbyname() 
function is not requested to the linker, and therefore simply trying to 
link with wsock32 fails.
4. After fixing 1, 2, and 3, the resulting cpio.exe file fails to 
extract valid cpio archives printing "cpio.exe: premature end of file". 
It also fails to create a valid cpio archive as when I attempt to use 
the native Fedora cpio it fails printing "cpio: premature end of file". 
I then created a similar cpio archive with the native Fedora cpio and 
found the following file size differences:
cpio.exe built archive file size: 84323
cpio built archive file size: 81920

Solutions:
1. Seems to be fixed with commit 
3a7a1820d4cecbd77c7b74c785af5942510bf080, so that's one down. The rest 
are still an issue with the latest git revision.
2. I put a #ifdef HAVE_READLINK around the readlink() call and set 
link_size = -1. This may not be a proper solution, but it works for 
building with MinGW.
3. Including winsock2.h in lib/rtapelib.c and linking cpio.exe with 
wsock32 fixes the issue.
4. Unknown. Perhaps my configure line is not correct?

I would appreciate any comments on these issues.

Thanks,
Michael
