Are these options really required with the DJGPP2 targeted GCC ? With
the Linux target the '--enable-__cxa_atexit' may be motivated but does
the DJGPP2
target C library support this feature? If all there really are
required, things are ok. But somehow this reminds me about people once
putting all kind of commands
into their CONFIG.SYS and AUTOEXEC.BAT only because their friends told
those being "useful"... But nobody seemed to understand what they were
and why
they must be put there. The configure example in the GCC manual:
"configure --target=my_chosen_target" for a crosscompiler could be a
better model for the
configure command than one seen with 'gcc -v' with the native Linux GCC...
