It needs the file `info.info'. This file comes with the txi312b.zip
distribution and should already be in your `info' subdirectory.
Perhaps you have some installation snafu; see section 6.9 of the DJGPP
FAQ list.

Type "info gcc invoking submodel i386" and read the description of the
option -mregparm. Warning: if you compile some of your sources with
this switch, you cannot call library functions from those source
files!
A better way of achieving the same goal is to use the GCC inline
assembly facilities; see section 18.13 of the FAQ for more details.

No; see section 17.5 of the DJGPP FAQ list.

Type "info know hidden djgpp" and read there.

Please don't do that! DJGPP.ENV is very central to the smooth
operation of the package, and it is very easy to break your
installation by editing it. You should NOT need to edit DJGPP.ENV at
all; it is already set in a way that allows to solve almost every
problem without touching DJGPP.ENV.
If you have specific problems that you think require you to edit
DJGPP.ENV, please describe those problems here. It is almost certain
those problems can be solved by other means.

No, we don't; and neither should you. See section 8.13 of the DJGPP
FAQ list for the explanation and remedies.

Why don't you count dos4gw.exe? Please *do* count it, if you want the
comparison be fair.
Anyway, using the simple techniques described in section 8.13 of the
FAQ, I can make "Hello world" be 28KB on disk.

Please in the future make the small effort to include your correct
address in the message. Some of us reply to way too many message, and
cannot afford manually editing the headers.
