Okay. This means GCC is trying to link against a profiling library. Most
likely, this is due to it not using your specs file, but rather its builtin
one. Compile with `-v' and see if you see the line "Using builtin specs",
and if so, make sure that %DJDIR%/lib is along the LIBRARY_PATH specified
for GCC in DJGPP.ENV. (The README erroneously instructs you to remove it.)

As a quick-and-dirty fix, you can copy %DJDIR%/lib/libc.a to
%DJDIR%/lib/libc_p.a, or get a profiling library from Tom Demmer's patch
site and install it as libc_p.a. (This would have the addition of letting
you get profiling info on library functions.)
