           Summary: [4.6] boehm gc incorrectly compile using
                    __declspec(dllexport) on i686-w64-mingw32 target
           Product: gcc
           Version: 4.6.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: boehm-gc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: blakawk@gentooist.com


When trying to build a cross compiler for i686-w64-mingw32 target, the boehm-gc
library is built with __declspec(dllexport) while --disable-shared was
specified on the command line, which leads to programs linked with resulting
GCJ failing to link with undefined references to ___imp_GC functions.

The build should instead define GC_NOT_DLL when building the GC static library
to avoid theses link failures.

The error encountered was:
# i686-w64-mingw32-gcj -v -o HelloWorldJava.exe HelloWorld.java
--main=HelloWorld

Proposed patch

This "ugly" patch fixed the problem by defining GC_NOT_DLL for boehm gc build.

well, the underlying issue is here the wrong assumption of the meaning of _DLL
macro for Windows targets.  This macro gets defined, if shared (means DLL)
version of msvcrt.dll is used and has nothing to do with the fact, if a DLL is
build, or not.

I will prepare a patch for it
