Comment(by Zara <zaravalle_at_[hidden]>):

 Solution (apparently) found: The current file documents something
 introduced for GCC 3.4:
 >>    // NOTE: Explicitly qualifying "bits_per_block" to workaround
 >>    //       regressions of gcc 3.4.x
 >>    const bool no_padding =
 >>        dynamic_bitset<Block, Allocator>::bits_per_block
 >>        == CHAR_BIT * sizeof(Block);

 Removing the explicit qualification compiles with GCC 4.3. To be tested:
 does the compiled object work OK?

 >>    const bool no_padding = bits_per_block == CHAR_BIT * sizeof(Block);
