#error is usually a signal that the program should not
compile. Strictly speaking, a C90 compiler is not
required to fail translation, but this was changed
under C99.

gcc isn't sentient, but it often shows more intelligence
than the people using it. ;-)

This one is expected.

Either you have a broken version of gcc, or your source
code above is not that of a.c.

This is a subtle requirement of the C language. Source
must end with a newline. Very few compilers enforce it.
gcc is simply warning you about it. If you didn't have
the #error directive, it would still compile. But the
solution is simple: add a newline.
The requirement stems from the fact that text streams
require a newline on some implementations. [There are
still line printers in this world that won't print
a line of text until it receives a newline.]
Note that some text editors give you the option of
always adding a newline at the end of a file.
