[PATCH] Fix Ada bootstrap failure on Cygwin since switch to C++11 (PR98590)
This fixes the bootstrap failure with Ada on Cygwin since the switch to C++11. The configure checks detect that fileno_unlocked () is present, but when Ada's cstreams.c is compiled in C++11 mode, does not declare it, causing a hard error. Fixed by defining _GNU_SOURCE before including .
