Summary: Setting breakpoint in form of <module>!<id> doesn't work
           Product: Wine
           Version: 0.9.10.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-debug
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hi,
breakpoint command in winedbg should accept identifier in form <module>!<id>:
"-Identifiers can take a '!' in their names. This allow mainly to access symbols
from different DLLs like USER32!CreateWindowExA." - from Wine Developer's Guide.
But when I enter such expressions winedbg seems to process only part before '!'.

Example:
<in some debugging session>:
Wine-dbg>b advapi32!HeapFree
No symbols found for advapi32
Unable to add breakpoint, will check again when a new DLL is loaded
syntax error

I've tried to investigate this issue and seems that problem somewhere in winedbg
Yacc rules. When I've changed 'identifier' rule in dbg.y
From:
identifier:
      tIDENTIFIER               { $$ = $1; }
    | tPATH '!' tIDENTIFIER     { .... }
To
identifier:
      tIDENTIFIER               { $$ = $1; }
    | tIDENTIFIER '!' tIDENTIFIER     { ... }

winedbg began to accept such breakpoint commands properly:
Wine-dbg>b advapi32!HeapFree
Many symbols with name 'advapi32!HeapFree', choose the one you want (<cr> to abort):
[1]: 0x7f9baa70 HeapFree in advapi32
[2]: 0x7f9baa70 HeapFree in advapi32

But it still does case-sensitive search through modules and 'ADVAPI32!HeapFree'
doesn't work, but, as far as I've understood from Developer's Guide example, 
case-insensitive search is expected.
