[Bug java/14074] New: libgcj

[scaccopardo at tiscali dot it]

Hi,

I followed instructions and this time
"make" started classes compilation!!!

But...

$ pwd
/usr/build

$ /usr/src/gcc-3.3.1-3/configure --enable-threads=win32 --enable-sjlj-
exceptions --enable-libgcj --enable-languages=c,c++,java
 --prefix=/usr/local

Now I got this error:

I tried to re-./configure with enable-threads=posix but I got
the same error...So I decided to see source code.

"GC_CreateThread" prototype is under #define(s): (in gc.h)

#if defined(GC_WIN32_THREADS) && !defined(__CYGWIN32__) && !defined(__CYGWIN__)

   GC_API HANDLE WINAPI GC_CreateThread(
      LPSECURITY_ATTRIBUTES lpThreadAttributes,
      DWORD dwStackSize, LPTHREAD_START_ROUTINE lpStartAddress,
      LPVOID lpParameter, DWORD dwCreationFlags, LPDWORD lpThreadId );
[...]

so I think __CYGWIN32__ or __CYGWIN__ are #defined.

Shouldn't I use win32 threads or is there a ./configure option
should I use ?
(Did I have to clean before re./configuring with posix threads and how?
Compilation took really a lot of time and I'd like not to loose compilation 
results...)

Thanks in advance,

Davide
