I'm trying to make Profili 2 Pro work in wine. So far I reached the point where
it works, but there is an issue when application tries to execute is *.bat
wrapper.

I get this error (more complete trace is attached):
Can't recognize 'C:\ProfiliProV2\xf.bat" "C:\ProfiliProV2\XFoil.exe' as an
internal or external command, or batch script.

With trace enabled, I get:
wmain Full commandline 'L"C:\windows\system32\cmd.exe /c
"C:\ProfiliProV2\xf.bat" "C:\ProfiliProV2\XFoil.exe""'

WCMD_DumpCommands Parsed line:
WCMD_DumpCommands 0x121c18 0 00 (nil) L"C:\ProfiliProV2\xf.bat"
"C:\ProfiliProV2\XFoil.exe" Redir:L""

command has stripped first and last " but the quotes in the middle remained

WCMD_process_commands Executing command: 'L"C:\ProfiliProV2\xf.bat"
"C:\ProfiliProV2\XFoil.exe"'

WCMD_execute param1: L":\ProfiliProV2\xf.bat"", param2:
L"C:\ProfiliProV2\XFoil.exe"

param1 is missing 'C' as first character and has surplus " at the end

WCMD_run_program first param='L"C:\ProfiliProV2\xf.bat
C:\ProfiliProV2\XFoil.exe"'

and looking for the command in that composed path fails (as expected):

Searching in 'L"C:\ProfiliProV2\xf.bat C:\ProfiliProV2\"' for
'L"XFoil.exe"'

The problem related to wcmdmain.c:wmain(...) around line 2590:

/* strip first and last quote characters if opt_s; check for invalid
       * executable is done later */
      if (opt_s && *cmd=='"')
          WCMD_strip_quotes(cmd);

before this, cmd is:
"C:\ProfiliProV2\xf.bat" "C:\ProfiliProV2\XFoil.exe"
after this, cmd is
C:\ProfiliProV2\xf.bat" "C:\ProfiliProV2\XFoil.exe
the quotes in the middle remains.

opt_s was not specified, but was triggered on by checks around 2450: there is
at least one quote (pass), there is a second quote(pass) and there is no more
quotes(fail) - the last one fails and sets opt_s. My guess would be that those
checks should be done on first argument, not all of them together.

The xf.bat is very simple wrapper:
%1 <XFoil.cmd >XFoil.out
exit
