"system" behaves differently since dune 3 (Windows only) #5523
Description
Some packages that use "system" could be compiled with dune version 2.9.3 and earlier, but no longer with dune 3.
e.g:
mesh-easymesh.0.9.5:
https://github.com/Chris00/mesh/blob/be7f043df3dedca862ad650538f8483855836c34/easymesh/dune#L20
Reproduction
opam install dune.3.0.3 mesh-easymesh.0.9.5File "easymesh/dune", line 17, characters 0-111:
17 | (rule
18 | (targets EasyMesh.exe)
19 | (deps easymesh.c)
20 | (action (system "%{cc} -o EasyMesh.exe easymesh.c -lm")))
(cd _build/default/easymesh && C:\Windows\system32\cmd.exe /c "cl -nologo -O2 -Gy- -MD -o EasyMesh.exe easymesh.c -lm")
The command ""cl -nologo -O2 -Gy- -MD -o EasyMesh.exe easymesh.c -lm" is either misspelled or could not be found
No errors with
opam install dune.2.9.3 mesh-easymesh.0.9.5or
opam install dune.1.11.4 mesh-easymesh.0.9.5similar:
