Subject:  impose a negativ-list of names we do not want to
X-Git-Tag: v8.0.0~21819
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8fa2d87351d2c4f1f64068db5e878d80fa839263;p=dealii.git

 impose a negativ-list of names we do not want to
 have in this file. this is due to a compiler bug in
 egcs 1.1.2, which does not gracefully handle local
 template classes if their name is globally defined,
 for example

 template <int dim> struct Y;
 struct X {template <int dim> struct Y{}; };
 X::Y<1> y;

 does not work. So we filter out these classes at
 present. A better way would certainly be to only
 allow those classes into the forward-declarations.h
 file that are global, but that would mean parsing
 the include files instead of just searching for
 small bits...
