Warning: skipping dependency checks. Note: checking out 'v0.1.0'. You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout. If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b new_branch_name HEAD is now at f77438f... noglobal take 2 hdr_histogram.c: In function ‘hdr_reset_internal_counters’: hdr_histogram.c:211:5: error: ‘for’ loop initial declarations are only allowed in C99 mode for (int i = 0; i < h->counts_len; i++) ^ hdr_histogram.c:211:5: note: use option -std=c99 or -std=gnu99 to compile your code hdr_histogram.c: In function ‘shift_lowest_half_bucket_contents_left’: hdr_histogram.c:385:5: error: ‘for’ loop initial declarations are only allowed in C99 mode for (int from_index = 1; from_index < h->sub_bucket_half_count; from_index++) ^ Error: Build error: Failed compiling object hdr_histogram.o
