I was right.

I have:
$ gcc -v
Reading specs from C:/MinGW/bin/../lib/gcc/mingw32/3.4.2/specs
Configured with: ../gcc/configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --enable-languages=c,c++,f77,ada,objc,java 
--disable-win32-registry --disable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter 
--enable-hash-synchronization --enable-libstdcxx-debug
Thread model: win32
gcc version 3.4.2 (mingw-special)

"gcc -std=c89 -E" on lt-usea.c has exactly one occurence of stat.h:
# 1 "C:/MinGW/bin/../lib/gcc/mingw32/3.4.2/../../../../include/sys/stat.h" 1 3

No declaration from it though.

That file is like this:

/*
 * stat.h
 *
 * Symbolic constants for opening and creating files, also stat, fstat and
 * chmod functions.
 *
 * This file is part of the Mingw32 package.

#ifndef __STRICT_ANSI__
/*stuff*/
#endif  /* Not __STRICT_ANSI__ */


So, no struct _stat or anything like it for me...
