No, it is not strange: indeed the MELT *branch* has a file contrib/MELT-Plugin-Makefile which is used for the *MELT* plugin (but is useless for the MELT *branch*, which has its own gcc/Makefile.in). But the MELT plugin is not useful for the MELT branch. When you build a gcc-melt from the MELT branch, there is no melt.so file involved, the melt-runtime.o is statically linked inside cc1 (and cc1plus, etc etc...) and the MELT runtime is automagically started as a pseudo-plugin without any dlopen-ing. the MELT initialization phase is indeed dlopen-ing MELT modules (as does the melt.so plugin for a regular GCC), because toplev.c of the MELT branch calls melt_initialize() and melt_finalize(). So, when building the MELT *branch* (which few people do), you don't need or use contrib/MELT-Plugin-Makefile. When I extract the MELT plugin from the MELT branch (e.g. for MELT plugin releases) with the procedure in https://groups.google.com/group/gcc-melt/msg/083091abb7f30c39?hl=en the MELT-Plugin-Makefile is becoming the Makefile for the extracted plugin. But the MELT branch don't need it, so it sits in rightly contrib/MELT-Plugin-Makefile > It seems that among all your gawk uses, including > make-warmelt-predef.awk and make-melt-predefh.awk > the only GNU specific feature is strtonum.
