+Subject: [PATCH 2/3] build: make nftables usable with mini-gmp
+
+libgmp usually compiles to >400KB which can put a burden on embedded
+device firmware especially if libgmp isn't used for other purposes.
+mini-gmp in contrast adds only ~30KB to the nft-binary itself.
+
+However mini-gmp does not support gmp_sscanf and gmp_printf.
+
+This patch:
+* Adds a configure flag --without-libgmp to select mini-gmp
+* Replaces the single gmp_sscanf occurence with mpz_set_str
+* Replaces calls to gmp_printf outside of pr_debug with
+ a minimalistic mpz_printf usable to format one mpz_t
+* Replaces gmp_vasprintf in erec_vcreate with vasprintf
+ and rewrites the single user of the gmp format-flags
+* Changes the parser token VERSION to IPHDRVERSION to avoid
+ clashes with the VERSION-define in config.h

-Subject: [PATCH 2/2] build: allow building with mini-gmp instead of gmp
-
-This introduces --without-libgmp which includes mini-gmp into nft
-(adding ~30k) but avoids linking libgmp which is >400k.
-
-This is useful for embedded distributions not using gmp otherwise.
-
-Note: currently --without-libgmp must be used with --disable-debug.
