It seems that most uses of `as_fn_append` correctly include a leading space before appending to a variable, however, there are several cases where this space has not been added which can lead to two arguments being concatenated:\n\n- https://github.com/python/cpython/blob/main/configure#L9617\n- https://github.com/python/cpython/blob/main/configure#L9735\n- https://github.com/python/cpython/blob/main/configure#L9780\n- https://github.com/python/cpython/blob/main/configure#L9821\n- https://github.com/python/cpython/blob/main/configure#L9862\n- https://github.com/python/cpython/blob/main/configure#L9903\n- https://github.com/python/cpython/blob/main/configure#L9944\n- https://github.com/python/cpython/blob/main/configure#L9996\n\nWhen compiling to Emscripten in Bazel, for example, I end up with `-sRELOCATABLE=1-Wstrict-prototypes` in one of my tests:\n```\nconfigure:9880: checking if we can enable /home/developer/.cache/bazel/_bazel_developer/25e07d78077dfe1eca932359d50e41ef/sandbox/processwrapper-sandbox/29/execroot/_main/external/emsdk/emscripten_toolchain/emcc.sh strict-prototypes warning\nconfigure:9900: /home/developer/.cache/bazel/_bazel_developer/25e07d78077dfe1eca932359d50e41ef/sandbox/processwrapper-sandbox/29/execroot/_main/external/emsdk/emscripten_toolchain/emcc.sh -c --sysroot=/home/developer/.cache/bazel/_bazel_developer/25e07d78077dfe1eca932359d50e41ef/sandbox/processwrapper-sandbox/29/execroot/_main/external/emscripten_bin_linux/emscripten/cache/sysroot -fdiagnostics-color -fno-strict-aliasing -funsigned-char -no-canonical-prefixes -Wall -iwithsysroot/include/c++/v1 -iwithsysroot/include/compat -iwithsysroot/include -isystem /home/developer/.cache/bazel/_bazel_developer/25e07d78077dfe1eca932359d50e41ef/sandbox/processwrapper-sandbox/29/execroot/_main/external/emscripten_bin_linux/lib/clang/19/include -Wno-builtin-macro-redefined -D__DATE__=redacted -D__TIMESTAMP__=redacted -D__TIME__=redacted -O2 -g0 -fwasm-exceptions -pthread -sRELOCATABLE=1-Wstrict-prototypes -Werror -I/home/developer/.cache/bazel/_bazel_developer/25e07d78077dfe1eca932359d50e41ef/sandbox/processwrapper-sandbox/29/execroot/_main/bazel-out/k8-fastbuild/bin/python/libpython.ext_build_deps/libffi/include conftest.c \u003e\u00265\nemcc: error: setting `RELOCATABLE` expects `bool` but got `str`\n```\n\n### CPython versions tested on:\n\n3.12\n\n### Operating systems tested on:\n\nOther\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-120822\n* gh-120985\n* gh-120986\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/allsey87","@type":"Person","name":"allsey87"},"datePublished":"2024-06-18T09:32:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":7},"url":"https://github.com/120671/cpython/issues/120671"}
