To: libstdc++, gcc-patches
The embedded tzdata.zi causes new build failures for small targets.
Tested x86_64-linux, built on avr and msp430-elf.
-- >8 --
The string literal containing the static tzdata.zi information is too
large for some targets, so do not enable it by default for avr-*-* and
msp430-*-*.
libstdc++-v3/ChangeLog:
* acinclude.m4 (GLIBCXX_ZONEINFO_DIR) [avr-*-*, msp430-*-*]: Set
embed_zoneinfo=no
* configure: Regenerate.
