// g++ 1.36.1 bug 900210_05
|
3 |
|
|
|
4 |
|
|
// Section 18.3 of the 2.0 Reference Manual says "An implementation
|
5 |
|
|
// providing { anachronistic features } should also provide a way for
|
6 |
|
|
// the user to ensure that they do not occur in a source file."
|
7 |
|
|
|
8 |
|
|
// The *only* proper way to "ensure" an absence of anachronstic features
|
9 |
|
|
// is for C++ language processors to generate errors (rather than just
|
10 |
|
|
// warnings) when such features are used. These errors could perhaps be
|
11 |
|
|
// triggered by some set of command line options, or by the absence of
|
12 |
|
|
// certain command line options. (For g++, the -pedantic and -traditional
|
13 |
|
|
// options come to mind.)
|
14 |
|
|
|
15 |
|
|
// The use of errors rather than warnings is important because errors
|
16 |
|
|
// usually result in nonzero exit status codes for language processors
|
17 |
|
|
// and these nonzero exit stati can be automatically checked during
|
18 |
|
|
// normal execution of a Makefile.
|
19 |
|
|
|
20 |
|
|
// cfront 2.0 provides the +p option which causes errors to be generated for
|
21 |
|
|
// all cases of anachronistic usage.
|
22 |
|
|
|
23 |
|
|
// g++ generates neither errors nor warnings for such usage, even when the
|
24 |
|
|
// -ansi and -pedantic options are used.
|
25 |
|
|
|
26 |
|
|
// Cfront 2.0 passes this test.
