Thanks Hans-Bernhard:

.com file not are my final objective. My Objective is creating a small
operating system to educational purposes, and I need compile C programs
with GCC that can execute in booting time. 32 bits can be an option, if
I can obtain documentation about that ("Hello world with LGTD").

To this moment I have a IPL program with a group small routines in
assemble compiled/linked with "as/ld". This is working fine. But link
that with C compiled code is the WALL to climb now.

I am a experimented C programmer and Operating System teacher.

Thanks for your help.

Att.
Diego Cueva.

Of course it doesn't --- you're using entirely the wrong tool for the
job.  DOS .com files aren't 32-bit code, and no, there's no simple
machine instruction to turn the machine into 32-bit mode, either.

If DOS-style .com files are what you want to create, DJGPP is not the
tool you need.

... You're managing just fine via the gateway between the newsgroup and
the mailing list.
