[patch] libstdc++/65754 missing exports for fstream constructors

Jonathan Wakely Mon, 13 Apr 2015 11:29:31 -0700

This fixes a regression I introduced by not exporting some of the
fstream constructors (the C2 base object ones) when using the new
std::string. Sorry for not finding this myself before the RC.


All the recently-updated baseline_symbols.txt files need updating. I
did this with sed and sort, and verified that the x86_64-linux-gnu and
powerpc64-linux-gnu ones are identical (except for the TLS call_once
symbols) to the output of 'make new-abi-baseline'. I have not checked
the baselines for other arches, only inspected the diff visually.

This really needs to go on trunk and gcc-5-branch.
