error: 'SSIZE_MAX' undeclared in utils.c
It seems commit 9b850f92 breaks compilation with mingw-w64 (at least with the GCC 4.9.1 based we plan to use in Tor Browser based on ESR 31). The error message is:
src/common/util.c: In function 'esc_for_log':
src/common/util.c:1211:3: error: 'SSIZE_MAX' undeclared (first use in this function)
src/common/util.c:1211:3: note: each undeclared identifier is reported only once for each function it appears in
