I have tried to compile the the repository code of libc and the compiler stoped with the follwing error message:

C:/DJGPP-2.05/BIN/make.exe -C common
gcc ... -c dbgcom.c
dbgcom.c: Assembler messages:
dbgcom.c:1342: Error: symbol `.Ldoes_not_has_read_right' is already defined
dbgcom.c:1346: Error: symbol `.Ldoes_not_has_write_right' is already defined
make[3]: *** [../../makefile.inc:90: dbgcom.o] Error 1
make[2]: *** [makefile.sub:2: all_subs] Error 2
make[1]: *** [../makefile.lib:7: all] Error 2
make: *** [makefile:45: subs] Error 2

I have tried this using gcc1010 and gcc1020.  Both fails.  If I use gcc920
everything works fine.  In all cases bnu234b has been used and no other one
has been tried.


Of course there are a lot of other warnings that aborts the compilation like:

or:
d:/djgpp/include/io.h: In function '_chmod':
_chmod.c:28:14: warning: array subscript 1 is outside array bounds of 'int[1]' [-Warray-bounds]
    28 |     r.x.cx = *(&func + 1);  /* Value to set */
       |              ^~~~~~~~~~~~
_chmod.c:14:34: note: while referencing 'func'
    14 | _chmod(const char *filename, int func, ...)
       |                              ~~~~^~~~

The -Warray-bounds appears quite a lot due to our way to address neighborhood variables as can
be seen in the example above.  May be some with some spare time can fix these occurencies.

Juan M. Guerrero
