link failure with cvs HEAD urxvt

[Jukka Salmi]

Hi,

today's HEAD sources fail to build on my NetBSD system; I'm getting
lots of undefined references:

[...]
g++ -DHAVE_CONFIG_H  -g -O3 [...] -c rxvttoolkit.C
g++ -DHAVE_CONFIG_H  -g -O3 [...] -c rxvtutil.C
g++ -DHAVE_CONFIG_H  -g -O3 [...] -c iom.C
g++ -DHAVE_CONFIG_H  -g -O3 [...] -c keyboard.C
g++ -DHAVE_CONFIG_H  -g -O3 [...] -c fdpass.C

rxvt.o: In function `main':
/usr/local/src/rxvt-unicode/src/rxvt.C:59: undefined reference to `__cxa_begin_catch'
/usr/local/src/rxvt-unicode/src/rxvt.C:59: undefined reference to `__cxa_end_catch'
[...]

Using g++ instead of gcc for linking solves the problem. However, since
I'm not autocapable I don't know how to correctly fix configure.ac.
Help and hints are appreciated.


TIA, Jukka
