Just as a datapoint; I've confirmed that this fixes my issue when compiling on an older centos build 👍

Before - failure:

21:14:46 ../.././include/ruby/internal/core/rregexp.h:106:5: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
21:14:46 closure.c: In function ‘initialize’:
21:14:46 closure.c:279:60: error: ‘data’ undeclared (first use in this function)
21:14:46 closure.c:279:60: note: each undeclared identifier is reported only once for each function it appears in
21:14:46 make[2]: *** [closure.o] Error 1

After - success:

compiling closure.c

installing default gems from ext:   
...
                                    fiddle 1.1.0
