Subject: 30.0.50; Compilation wrong error match
Date: Fri, 10 Mar 2023 14:31:23 +0100

Hi:

Using the compilation buffer I get a pattern highlighted but it is not
an error.

I would like to know which of the patterns in
compilation-error-regexp-alist-alist matched this.

This is the line that matches:

```
C:\Program Files (x86)\link.exe /ERRORREPORT:QUEUE /OUT:"E:\Repository.dll" /INCREMENTAL /NOLOGO "C:\Users\somefile.lib" user32.lib advapi32.lib /MANIFEST /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /manifest:embed /DEBUG:FASTLINK /PDB:"somefile.pdb" /SUBSYSTEM:CONSOLE /LARGEADDRESSAWARE /OPT:NOREF /OPT:NOICF /TLBID:1 /DYNAMICBASE /NXCOMPAT /IMPLIB:"somefile" /MACHINE:X86 /SAFESEH:NO /machine:X86 /DLL
```

The highlight goes from the beginning of the line up to /TLBID:1

And I think that compile-mode gets confused by the `/ERRORREPORT + something:1`.

If there is some function to find the pattern matching and help on this,
please just tell me and I will try to fix it myself. I tried a loop more
or less like:

(dolist (var compilation-error-regexp-alist)
     (re-search-forward (car (alist-get var compilation-error-regexp-alist-alist)) nil t))

But it does not match with any pattern, so... no idea
