+Subject: Build: Include gperf-generated code directly.
+
+Previously we built the generated code separatly and then linked to
+it.  However, this caused problems with certain compilers and gperf
+versions.  This change includes the generated code directly in
+svgtiny.c instead, which is the only place its used.
