Hi Dan,

 I'm trying to compille bootJVM with MSVC 6.0.

 Tim's. suggestion (long long = __int64) works fine.

 I didn't translate the configuration and build scripts into .bat files 
for Windows, I just
 ran the scripts in Cygwin, in order to have the source tree available 
and made a
 "console application" in MSVC.
 I'm not much familiar with InstallShield scripts and honestly I'd 
prefer to dedicate
 my spare time to work on the source code side (C is my "daily bread").

 Right now I got some problems which I'm planning to solve during the 
 here are two examples:

 rvoid argv_init(int argc, char **argv, char **envp)
    rchar *chkjh;
    chkjh =  (rchar *) rnull;
    rchar *chkcp;     <--- MSVC flags this as a compilation error

..\jvm\src\argv.c(127) : error C2275: 'rchar' : illegal use of this type 
as an expression

typedef struct
    u1 tag;
    u2 string_index;

    struct LOCAL_String_binding
                                                   <-- MSVC doesn't like 
an empty struct
    } LOCAL_String_binding;
} CONSTANT_String_info;

..\jvm\src\classfile.h(1031) : error C2059: syntax error : '}'

I have to add "int foo;" in order to proceed

Certainly, the code will have to be slightly adjusted for portability.

Let me proceed and after the weekend I'll write a report.
