* util.c: qsort_s in C11nobu2018-09-091-4/+21
| | | | | | | | | | | | | * configure.ac: macro for C11 to use qsort_s. * util.c (ruby_qsort): fix for C11 qsort_s. the comparison function for MSVCRT qsort_s is compatible with BSD qsort_r, but not with C11 qsort_s, in spite of its name. note that mingw defines __STDC_VERSION__ but uses qsort_s in MSVCRT, so the MSVCRT block needs to preced the C11 block.
