>Description:
The text message after the #error and/or #warning pre-processor directives should just print out the literal text. gcc 2.* and gcc 3.* generate a pre-processing-time error if the text contains an English contraction like "can't" or "shouldn't" - which (conceptually) has mis-matched single-quotes
Attachment is .c file with NO #includes referenced; it is free-standaing as it is.
Such source is accepted as legal (i.e. swallowed without complaint) with other compilers I've tried.
