mingw build failing

[xangelix]

Hopefully this issue is meaningful, as my knowledge on mingw and rust cross-compilation is weak, but I am having many missing library errors when compiling to the x86_64-pc-windows-gnu target from linux, such as

warning=libesedb-20230824/libcerror/libcerror_error.c:34:2: error: #error Missing headers stdarg.h and varargs.h
warning: libesedb-sys@0.2.0:    34 | #error Missing headers stdarg.h and varargs.h
warning: libesedb-sys@0.2.0:       |  ^~~~~

If additional guidance could be provided it would greatly be appreciated-- to my best knowledge I have libc properly installed in mingw, and think it might be an issue with the build script.
