Subject: [PATCH] re PR gcov-profile/81080 (target libgcov not built with large
file support)
2017-06-21 Richard Biener <rguenther@suse.de>
PR gcov-profile/81080
* configure.ac: Add AC_SYS_LARGEFILE.
* libgcov.h: Include auto-target.h before tsystem.h to pick
up _FILE_OFFSET_BITS which might differ for multilibs.
* config.in: Regenerate.
* configure: Likewise.
