Bug#164872: g++-3.2: Defines _GNU_SOURCE

[Mark Brown <broonie@sirena.org.uk>]

Package: g++-3.2
Version: 1:3.2.1-0pre3
Severity: normal
Tags: upstream

GCC 3.2 appears to define _GNU_SOURCE unconditionally.  This is somewhat
unhelpful if one wishes to use the feature selection macros provided by
glibc to choose which APIs are provided by the library.

This appears to be a long-standing upstream decision:

   http://gcc.gnu.org/ml/gcc/2000-11/msg01084.html

although I can't see any discussion of motivation for this.

Grovelling around on the GCC website it appears that the issue is that
libstdc++ needs _GNU_SOURCE although I can't quite be sure about that.
