Then something else changed on your machine, because the compiler is
now unusable:

This means it didn't find it in any of the places it knows to look.
When it finds the library, it displays its full absolute file name,
like this, for example (from my machine):

  D:/usr/bin/../lib/gcc/mingw32/3.4.2/../../../libmingw32.a

You need to find out what changed on your machine lately that causes
this problem.  Perhaps some environment variables or a change in
directory structure, or some Cygwin-specific change?

Why, by installing the native MinGW port of GCC, of course.  The
Cygwin project doesn't really care about the native builds, so relying
on it for native builds is not a good idea in the long run.
