+Subject: [PATCH] configure.ac: use link instead of compile for gcc flags test
+
+The logic that tests whether gcc supports or not certain flags uses
+AC_COMPILE_IFELSE(). However, when checking for stack smashing
+protection support, an AC_LINK_IFELSE() test is needed, since the
+build might work but not the link stage if certain libraries are
+missing for proper stack smashing protection support.
+
+Therefore, this commit switches to use AC_LINK_IFELSE().

+Subject: [PATCH] configure.ac: correct stack protector check
+
+If a used toolchain accepts the `-fstack-protector` option but does not
+provide a stack smashing protector implementation (ex. libssp), linking
+will fail:
+
+ .libs/rpmio.o: In function `Fdescr':
+ rpmio.c:(.text+0x672): undefined reference to `__stack_chk_fail_local'
+ .libs/rpmio.o: In function `Fdopen':
+ rpmio.c:(.text+0xce9): undefined reference to `__stack_chk_fail_local'
+ .libs/rpmio.o: In function `ufdCopy':
+ rpmio.c:(.text+0x10f7): undefined reference to `__stack_chk_fail_local'
+ ...
+
+This is a result of testing for `-fstack-protector` support using a main
+that GCC does not inject guards. GCC's manual notes that stack protector
+code is only added when "[functions] that call alloca, and functions
+with buffers larger than 8 bytes" [1]. This commit adjusts the stack
+protector check to allocate memory on the stack (via `alloca`).
