exe should be gcc, gxx (DOS), g++ (Win), not gpp -- preprocessor only 

path should be c:/progapp/djgpp/include/cxx/3.23/ not
c:/progapp/djgpp/lang/cxx/3.23/

unless paths changed between 3 and 4 

check with gxx --print-search-dirs

check DJGPP env var set

c:\ > cd c:\progapp\djgpp
c:\ > echo %DJGPP%
c:\progapp\djgpp > set DJGPP=c:/progapp/djgpp/djgpp.env

check header.gcc in the following include dirs

c:\progapp\djgpp > find . -name header.gcc
./lib/gcc/djgpp/4.32/include/header.gcc
./include/cxx/4.32/bits/header.gcc
