AC_OUTPUT

# Windows Erlang build tools wrap Microsoft's linker and compiler just enough
# to be able to build Erlang/OTP successfully, but not enough for full
# compatibility with GNU AutoTools. The MS VC compiler and linker are
# hidden from autotools in Erlang's cc.sh and ld.sh wrappers. GNU autoconf
# identifies this dastardly mix as a unix variant, and libtool kindly
# passes incorrect flags and names through to the MS linker. The simplest fix
# is to modify libtool via sed to remove those options.
# As this is only done once at first configure, and subsequent config or source
# changes may trigger a silent reversion to the non-functioning original.
# Changes are;
# 1. replace LIB$name with $name in libname_spec (e.g. libicu -> icu) to ensure
#    correct windows versions of .lib and .dlls are found or generated.
# 2. remove incompatible \w-link\w from archive_cmds
# 3. remove GNU-style directives to be passed through to the linker
# 4. swap GNU-style shared library flags with MS -dll variant
# This obscene hackery is tracked under COUCHDB-440 and COUCHDB-1197.
