I just tried this on an emulated system (looks like an A1200 with a 040
and 128MB RAM) running 5.99.18.

No problem to build.

nmap depends on pcre. Building pcre failed with

c++ -DHAVE_CONFIG_H -I.      -O2 -MT pcrecpp_unittest.o -MD -MP -MF 
.deps/pcrecpp_unittest.Tpo -c -o pcrecpp_unittest.o pcrecpp_unittest.cc
pcrecpp_unittest.cc: In function 'int main(int, char**)':
pcrecpp_unittest.cc:1276: internal compiler error: Segmentation fault

The system is still running, the failed cc1plus process churns CPU at 100%.
An attached gdb shows:

This might be still a problem of the emulation..
