+Subject: [PATCH] meson.build: defaults to c99 for "build.c_std"
+
+Since Meson 0.51, there are special build options for "native:true"
+builds, prefixed with "build.".  This change breaks cross builds
+because `janet-boot/src_core_asm.c` is no longer built with `-std=c99`:
+
+FAILED: janet-boot.p/src_core_asm.c.o
+/usr/bin/gcc -Ijanet-boot.p -I. -I.. -I../src/include -pipe -D_FILE_OFFSET_BITS=64 -Wall -Winvalid-pch -O3 -pthread -DJANET_BOOTSTRAP -MD -MQ janet-boot.p/src_core_asm.c.o -MF janet-boot.p/src_core_asm.c.o.d -o janet-boot.p/src_core_asm.c.o -c ../src/core/asm.c
