Using -Wl will cause error and stop the complier.
For msvc the WL is for detailed error info , not for enter options.

I'm using GNU Awk 5.1.1, API: 3.1 (GNU MPFR 4.1.0-p13, GNU MP 6.2.1)
on msys
I saved the output of dumpbin
I find there are character escape problem.
On msys shell it shows "-bash: syntax error near unexpected token `then'"
But after using vc init script it entered to cmd.
The error become "'/{next}' is not recognized as an internal or external command,
operable program or batch file
I'm not sure where the problem is , but in "make" command the gawk never through error.
cl.exe .libs/localcharset.obj .libs/relocatable-stub.obj /WL /link /out:test.dll /DLL
using cl.exe .libs/localcharset.obj .libs/relocatable-stub.obj /WL /link /out:test.dll ".libs\\charset-1.dll.exp" /DLL /IMPLIB:".libs\\charset.dll.lib"
will return the charset-1.dll.exp is corrupt. Can't read from 0x96
Well my head is not clear. I'm going to sleep.
Conclusion: A symbol "@" in cl.exe parameter caused fatal error and the exp file looks wrong.
Maybe my modify is wrong. I know nothing about how to use export file with cl.exe
You can see without the exp file the cl works fine.
Anything past the /link is the options for linker.
