OK, I started learning it long ago, but I only study when I'm forced
to.  :-)

Anyway, I am trying to build c2ada.  I'd like to solve a problem without
getting attacked for the folly of wanting to translate C into Ada, so
I'm asking here instead of in comp.lang.c  :-)

What should I do about this:

gbmsrv1:/usr/tools/bin/c2ada 259 -> make
gcc -g -W -Wimplicit -Wreturn-type -MMD -DDEBUG -DHAVE_CONFIG_H
-I/usr/tools/bin/python1.5/Include -I/usr/tools/bin/python1.5
-DPPATH=\":/usr/tools/bin/python1.5/Lib\"   -c htype.c -o htype.o

I suppose I need to change an environment variable or a -I somewhere,
but how do I figure out where and what to change it to?
