There's some discrepancy in what you tell above: you are talking about
GCC version 2.7.2.1, but the GCC binary distribution you downloaded,
gcc2952b.zip, is version 2.95.2 of GCC.
Is it possible that you had an older version of GCC installed on this
machine, and that you didn't remove that old installation before
installing the new one? If so, you want to remove everything and
reinstall, since it's quite possible that your problems all stem from
mixing two different versions of GCC.

This is okay.

This is not 100% okay: you need to say c:\programs\gcc\bin and
c:\programs\gcc\djgpp.env, respectively. The drive letter must be
included.

This is okay as well. (But note that your version of EMM386 only
supports 32MB of extended memory, instead of all the 48MB you have.)

Add -v to the GCC command line and watch what does it say about the
specs file. If it says "Using built-in specs", you have an
installation problem that causes the above problem as well.

That is the correct place of cc1.exe; do NOT copy or move it
anywhere else.

The size of the program on disk is not important, since it is loaded
into extended memory, not into DOS memory.
The memory size is not your problem. You need to find out why didn't
GCC find cc1.exe when it was in the lib\gcc-lib\djgpp\2.952\
subdirectory. Please remove the copy of cc1.exe you put into bin for
the rest of your digging into this problem.

No, please do NOT edit DJGPP.ENV. This line is correct: it tells
DJGPP programs to compute the value of DJDIR by taking the leading
directories part of the value of the DJGPP variable, and convert the
backslashes into forward slashes while at that.
In other words, in your case, DJDIR will have the value
c:/programs/gcc, once you put the drive letter into the DJGPP
variable. This is what the rest of DJGPP programs expect.

Do NOT edit it!

If the above doesn't help, add -v to the GCC command line, and post
here everything that the compiler prints.

GCC can run in both environments: native MS-DOS and Windows DOS box.
