Subject: what is ___gxx_personality_v0 ?

Hello,

I will appreciate any help or comment.

When I call :    gcc.exe -o test.exe test.cc foo.cc
gcc tells me :

C:/djgpp/tmp/ccMugof3.o(.eh_frame+0x11):test.cc: undefined reference
to '___gxx_personality_v0'
collect2: ld returned 1 exit status

The sources are:

===== test.cc =====

int foo();

int main()
{
  return foo();
}

===== foo.cc =====

int foo()
{
  return 1;
}

===== end =====


(this is minimum code to reproduce that message, it needs two files,
one file alone will compile fine)

This is true for DJGPP zips of June 9-th, I don't have earlier
release now, but there were no any problems before.

I tried default installation, just unzip files and set environment.
This reproduces under both Win98 and WinXP, with DJGPP installed
freshly on both. Actually, only used bnu2112.zip,
djdev204_alpha_win2k.zip, gcc31b.zip and gpp31b.zip.

Anyway, it does not seem like "expected behavior".



If can be of any help, this is outcome of same command with '-v' added:
( gcc.exe -v -o test.exe test.cc foo.cc )

(BTW, anyone has idea what is "c:/djgpp/djgpp/include" which is
"ignored nonexistent" ? )
