[Sablevm-user] Request for help.

[Etienne M. G. <eg...@j-...>]

Hi there!

I am currently working on SableVM, completing the base functionality of
the interpreter (to support all bytecodes, and exceptions), and cleaning
up a few things (nostly related to portability and flexibility).

I need some help with the GNU configure magic.  There are a few system
properties that I can deduce using simple C programs running on the
target platform.  Other things, I do not know how exactly to automate
them.  But mostly, I do not know how to get GNU configure to run these
programs and extract the results and put them into config.h.

Here is an example of a property I can deduce easily with a program:
support for labels as values (e.g. "&&label").  It the program compiles,
it is supported, if not, it's not.

Something harder to deduce: what is the name of the signed 32 bit
integer type?  (is it "signed int", "signed long", "signed short", ...)

Anybody knows about this stuff?  [I have no experience with M4, and
writing configure macros,...]

Thanks in advance,

Etienne
