It is not significant.

This is okay, but I suggest to put the C:\PROGRAMS\GCC\BIN directory
first, before \DOS and the rest.

This is okay.

These two worry me (as does \PROGRAMS\G77\BIN in your PATH).  Do you
have a separate installation of g77, the GNU Fortran 77 compiler,
somewhere on this system?  If you do, it is quite possible that this
is the source of your problems: g77 relies on GCC as its back-end, so
perhaps you do have another version of gcc unbeknownst to you.

If you do have g77 and another version of GCC installed, you will have
to arrange two batch files to set up the environment for each one of
them, and take care that environment variables such as PATH, LIB, and
LIBRARY_PATH are never set up for g77 when you work with DJGPP, and
vice versa.

Note the version of GCC: it's 2.7.2.1, not 2.95.2, and it has a .f.1
suffix.  I'm now quite convinced that you *do* have another,
incompatible version of GCC on that machine.

And here's my evidence: see that -D__EMX__ switch?  It tells that you
have and EMX port of GCC, probably for the g77 version you use (or
used in the past) lurking somewhere on your disk.  Since
\PROGRAMS\G77\BIN is earlier on the PATH than the DJGPP's bin
subdirectory, when you type "gcc -v hello.c", you actually invoke that
older EMX-compiled GCC.  And that is what gives you trouble.

Solution: you need to arrange a way to switche between the g77
environment and the DJGPP environment.  They use different ports of
two different and incompatible versions of GCC.
