Bug #1130: [PATCH] extern rb_thread_blocking_region_begin/end
http://redmine.ruby-lang.org/issues/show/1130

Author: Aman Gupta
Status: Open, Priority: Normal
Category: core, Target version: 1.9.1
ruby -v: ruby 1.9.1p0 (2009-01-30 revision 21907) [x86_64-linux]

rubysig.h uses:

RUBY_EXTERN struct rb_blocking_region_buffer *rb_thread_blocking_region_begin(void);
RUBY_EXTERN void rb_thread_blocking_region_end(struct rb_blocking_region_buffer *);

which compiles and links, but does not run:

/tmp/ruby19/bin/ruby: symbol lookup error: ext.so: undefined symbol: _Z31rb_thread_blocking_region_beginv

this patch fixes the issue:
