I was mystified by this comment in Makefile.shlib:
# We need several not-quite-identical variants of .DEF files to build
# DLLs for Windows. These are made from the single source file
# exports.txt. Since we can't assume that Windows boxes will have
# sed, the .DEF files are always built and included in distribution
# tarballs.
ifneq (,$(SHLIB_EXPORTS))
distprep: lib$(NAME)dll.def lib$(NAME)ddll.def
...
This doesn't make much sense (anymore?) since MinGW surely has sed and
MSVC doesn't use this (and has Perl). I think this is a leftover from
various ancient client-only ad-hoc Windows build provisions (those
win32.mak files we used to have around). Also, the ddll.def (debug
build) isn't used by anything anymore AFAICT.
I think we can clean this up and just have the regular ddl.def built
normally at build time if required.
Does anyone know more about this?
