Summary0035744: Windows compiler doesn't see simlink as an executable
DescriptionFPC can use external executable, for example, C:\lazarus\fpc\3.3.1\bin\i386-darwin\i386-darwin-ld.exe for cross-compilation only if this file is hard-linked or copied. It doesn't find it if this is NTFS simlink.

If file is copied or hard-linked then fpcdebuf.txt contains:
00008000:Searching file C:\lazarus\fpc\3.3.1\bin\i386-darwin\i386-darwin-ld.exe... found
00008000:(9017) Using util C:\lazarus\fpc\3.3.1\bin\i386-darwin\i386-darwin-ld.exe

However, if symlink was created instead, then
00008000:Searching file C:\lazarus\fpc\3.3.1\bin\i386-darwin\i386-darwin-ld.exe... not found
00008000:Searching file C:\lazarus\fpc\3.3.1\bin\x86_64-win64\i386-darwin-ld.exe... not found
10000002:Error: (9016) Util i386-darwin-ld.exe not found, switching to external linking
00008000:(9017) Using util i386-darwin-ld.exe
10000001:Fatal: (10026) There were 1 errors compiling module, stopping
10000001:Fatal: (1018) Compilation aborted
Steps To ReproduceMake sure that you have enough privileges for symlinks (run command prompt as Administrator), then:

> cd \lazarus\fpc\3.3.1\bin\i386-darwin
> mklink i386-darwin-ld.exe "C:\Program Files\LLVM\bin\ld64.lld.exe"
symbolic link created for i386-darwin-ld.exe <<===>> C:\Program Files\LLVM\bin\ld64.lld.exe
Additional InformationThis is an issue only for trunk/3.3.1.

Stable/3.0.4 doesn't have this issue.

May be it's also worth to accept *.bat and/or *.cmd files as external utility. They require different processing on Windows unlike *nixes where any script can be executable.
TagsNo tags attached.

It looks like the problem is in new implementation of FileExists. It doesn't work with default parameter FollowLink = True

FileExists('test.exe') returns False if 'test.exe' is correct symlink to existing file project1.exe.

Quick fix is to write FileExists('test.exe', False{FileLink}) instead. But this will not compile with 3.0.4.
