------- Comment #2 from rguenth at gcc dot gnu dot org 2007-10-12 14:38 ------- No, -pedantic gives an error. -pedantic -fpermissive gives a warning on the initialization but still an error on the FP literal:
tmp> g++-4.3 -c t.C tmp> g++-4.3 -c t.C -pedantic t.C:3: error: floating-point literal cannot appear in a constant-expression t.C:3: error: ISO C++ forbids initialization of member constant 'bar' of non-integral type 'const float' tmp> g++-4.3 -c t.C -pedantic -fpermissive t.C:3: error: floating-point literal cannot appear in a constant-expression t.C:3: warning: ISO C++ forbids initialization of member constant 'bar' of non-integral type 'const float' so I cannot get only warnings for this. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33750
