Description

I'm using cygwin, the mingw64 toolchain and I get the error.
It comes from Reloc.cygpath, that in turns calls get_output with use_bash:false.
The quick hack was to force it to use bash, but what could be done (in the non use_bash case) is to use Unix.create_process instead of Sys.command, since the former does not use a shell (no cmd.exe, so more than 8k for argv). See for example sys_command in https://github.com/coq/coq/blob/trunk/lib/cUnix.ml

Research direction

Start by tracing Reloc.cygpath into get_output, focusing on the non-use_bash path and its use of Sys.command. Compare that behavior with the sys_command example in Coq's lib/cUnix.ml; done means long commands work with the Cygwin and mingw64 toolchains without relying on cmd.exe's argument-length limit.
