Minor problem with #error directive

[Jim Wilson]

	This program:
	  #error This shouldn't cause a problem
	Causes this output:
	  error.cpp:1: unterminated string or character constant

Gcc is correct.  The ANSI C standard says that the text after the #error
directive must be a list of preprocessing tokens.  This is not the case
above, because you have an unterminated character constant, hence it
requires a diagnostic for the syntax error.
