-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 3/5] erec: use stdio vasprintf instead of gmp_vasprintf
+
+Use stdio's vasprintf instead of gmp_vasprintf which is not part
+of the mini-gmp function subset. Furthermore convert the only
+gmp-specific user and allow the compiler to verify format-strings.
