ld: virtual memory exhausted

[Ronald Bultje <rbultje@ronald.bitfreak.net>]

Hi,

I am getting this error when trying to compile mozilla 0.8:

[.....]
/usr/bin/ld -Bshareable /usr/lib/c++rt0.o -o libgklayout.so.1.0 <lots of
*.o files> -L../../dist/bin -ljsdom -lgkgfx -L../../dist/bin -lplds4 -lplc4
-lnspr4  -L../../dist/bin -lxpcom -lmozjs   -lm    
ld: virtual memory exhausted
gmake[2]: *** [libgklayout.so.1.0] Error 1
[.....]

Internet websites tell me something about increasing per process virtual
memory (would make sense), but how do I do that? Is this a sysctl-setting
or a kernel setting or something? Or does this have a totally different
cause (and solution)?
I have about 160 MB of swap and 80 MB of RAM on a Pentium 166 MHz with
openBSD 2.8.
I hope someone can help me. Thanks in advance,
