-Subject: [PATCH] CMakeLists: fix build with old compilers
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The librsync code uses some C99 constructs, but old compilers such
-as gcc 4.7 don't default to -std=c99. This commit makes sure librsync
-is built with -std=gnu99.
-
-Fixes:
-
-src/rabinkarp.h:82:5: error: ‘for’ loop initial declarations are only allowed in C99 or C11 mode
-     for (size_t i = len; i; i--) {
-     ^
-src/rabinkarp.h:82:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 to compile your code
