| # "%s/lib%s.def", "%s/%s.dll", "%s/lib%s.dll"), and when a .def | |
| # file is found, tccpe.c's pe_load_def reads the file's own | |
| # `LIBRARY <name>` directive via get_token() to get the DLL | |
| # filename to embed in the import table. Confirmed against | |
| # tinycc's own source that get_token() does NOT strip surrounding | |
| # double quotes, and the extracted name is used AS-IS with no | |
| # `.dll` extension appended. This OpenSSL 4.0.1 package's | |
| # libcrypto.def/libssl.def declare `LIBRARY "libcrypto-4-x64"` / | |
| # `LIBRARY "libssl-4-x64"` -- quoted, no extension -- so TCC | |
| # embeds the LITERAL string `"libcrypto-4-x64"` (quote characters | |
| # included, no `.dll`) as the runtime DLL name. `"` is illegal in | |
| # a Windows filename, so NO real file can ever match that name -- | |

| # output) for every TCC-linked test touching | |
| # crypto.ecdsa/crypto.rsa_pss/net.quic, confirmed via an actual CI | |
| # failure, regardless of what DLLs actually exist in bin\ (MSVC | |
| # is unaffected: it reads the DLL name from the .lib's own | |
| # build-time metadata, which is already a valid, unquoted, | |
| # extensioned filename). A file-aliasing workaround (mirroring | |
| # msvc-windows' crypto.lib/libcrypto.lib alias) CANNOT fix this -- | |
| # you cannot create a file whose name contains a literal `"` on | |
| # Windows. Fix at the source instead: rewrite each .def's LIBRARY | |
| # line in place, stripping the quotes and appending `.dll` if | |
| # missing, before TCC ever reads it. The rewritten name | |
| # (`libcrypto-4-x64.dll`) already exists as a real file in bin\ | |
| # (this package ships both v3 and v4 runtime DLLs side by side), | |
| # so no aliasing is needed once the .def itself is correct. | |
