Description of problem:
Linking against the MinGW port of bzip2 fails.  For start, code generated by
standard configure tests such as

AC_CHECK_LIB(bz2, BZ2_bzopen, ...)

fails.

Version-Release number of selected component (if applicable):
mingw32-bzip2-1.0.5-9.fc15

How reproducible:
Always.

Steps to Reproduce:
1. Create the following C code (essentially what configure creates as
conftest.c), calling it conftest.c:

char BZ2_bzopen ();
int main ()
{
return BZ2_bzopen ();
return 0;
}

2. Run
i686-pc-mingw32-gcc -o conftest.exe -g -O2   conftestc.c -lbz2

Actual results:
/home/yeti/tmp/ccEfyAbq.o: In function `main':
/home/yeti/xxx/conftest.c:5: undefined reference to `_BZ2_bzopen'
collect2: ld returned 1 exit status

Expected results:
It links and creates conftest.exe.

Additional info:
According to i686-pc-mingw32-nm, symbols in libbz2.dll.a bear extensions such
as @8, @10, etc., so BZ2_bzopen is there as _BZ2_bzopen@8.
