Subject: Re:  Assembly lang. calls from C++

First you have to know that the gas (gnu assembler) syntax is
different from MASM syntax. movl src,dst vs MOV DST,SRC. Furthermore
the gas syntax. Someone posted a reference to a place where
the assembler docs can be ftp'ed.

A more severe problem is the use of registers and addressing modes
as well as usage of interrupts. 

I cannot describe it all in detail here but it's not as easy
as you might think.
