// TO THE CYGWIN32 DESIGNERS! A BUG REPORT FOLLOWS.
// I have an IBM cloned PC with Win95 and the binary version
// of cygnus-win32-b17.1 ( 2.7.2-961023 )
// ------------------------------------------------------------
// I want to push a little for the opinion that those rather
// frequent enless loops are serious bugs. Specially in con-
// junction with the well known CTRL+C bug it is irritating.
// A compiler should behave like a patient teacher which does
// not rush out of the classroom when the student makes a
// foolish error. It took me hours to find the error below,
// buried as it was in a large code volume and with diffi-
// culties in reading the beginning of the error report.
// You always think the problem is sophisticated, not trivial.
// Please do not misunderstand me; I am otherwise a happy
// supporter of this free software. Thank you that have made it!
// ------------------------------------------------------------
// A "case" where an endless error report loop results from
// using "{" instead of ";" This may be more frequent than
// expected at a first glance. You often move the prototype
// xxx(int a); from the method definition xxx(int a){... }
// I wanted to reduce the code as much as possible but still
// having the loop error preserved. Because of that, if you
// correct the error you will have "ordinary", stable error
// messages. The original class code is without errors.
// Best Regards!
//
