Status changed from Closed to Assigned Assignee changed from kanemoto (Yutaka Kanemoto) to naruse (Yui NARUSE) ---------------------------------------- Backport #6748: bignum.c does not compile https://bugs.ruby-lang.org/issues/6748#change-28274 Author: pedz (Perry Smith) Status: Assigned Priority: Normal Assignee: naruse (Yui NARUSE) Category: Target version: I'm using the ruby_1_9_3 branch of ruby/ruby on github and bignum.c does not compile with an error that ffs is not defined. I'm on AIX 6.1 TL07 SP03. I assume HAVE_STRING_H is set (because AIX has string.h and strings.h) so ruby/ruby.h includes string.h but ffs is defined in strings.h. I noticed that time.c also uses ffs and it simply includes strings.h from within a #if construct.
