[Mingw-users] (newbie) invalid use of undefined type `struct stat'

[<phi...@ve...>]

I'm trying to build gsm-1.0-pl10 under cygwin with MinGW's executables =
(for example, "which gcc" shows that the MinGW gcc is being found; the =
make I'm using is apparently from MSYS).   I get a bunch of errors =
starting with several that look like:

src/toast.c: In function `update_mode':
src/toast.c:320: invalid use of undefined type `struct stat'

(The complete error chain is below, but I'm going on the principle of =
fixing cascading errors by trying to fix the first manifestation of =
trouble.)

Now, after doing a few searches i think this issue is probably related: =
http://www.winehq.com/hypermail/wine-patches/2003/01/0197.html .   Note =
the recent date and the comment "It's implemented similarly in mingw as =
well."   But I can't tell whether this issue was ever addressed in =
MinGW.

Does this issue look familiar to anyone?   Can someone point me in the =
right direction?

Thanks in advance,
Philip

VERSION OF EXECUTABLES
All MinGW stuff is dated 2002-09-07 on my system.

$ gcc --version
gcc.exe (GCC) 3.2 (mingw special 20020817-1)

$ make --version
GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.
Built for i686-pc-msys

$ ld --version
GNU ld version 2.13


WHAT'S BEING BUILT
I downloaded gsm from a link on gnophone.com, although that site seems =
to be down at the moment, and attempted to build it with make.   FWIW =
compilation had previously gotten a lot of warnings, which seem to be =
composed entirely of "#include_next is a GCC extension" and "ISO C89 =
does not support `long long'".   I also had to hack a =
-L"c:\dev\MinGW\include" into the linker flags to get it to compile.   =
Because I had also fixed another linker problem to get to this point, =
and because only get the warnings the first time i build after each =
"make clean", I assume the problem i'm having is at the linker step, =
although the messages seem more relevant to compilation (to me at =
least).
