Right, it was a bit misleading.

+# C-only warnings
+c_warning_flags = [
+ '-Wmissing-prototypes',
+ '-Wold-style-declaration',
+ '-Wold-style-definition',
+ '-Wstrict-prototypes',
+]
That looks ok but I wonder if we should also add '-Werror=vla' to it (
and remove it from common_warning_flags) to be in sync with what configure.ac
is doing:
"
PGAC_PROG_CC_CFLAGS_OPT([-Werror=vla])
# -Wvla is not applicable for C++
"
