This appears to be Windows specific. I don't have a Windows system to test
with. How does Visusal Studio handle #line entries with full path names? Are
they all escaped? Or better do they have to be?

Now this statement surprises me:

michael(at)feivel:~$ ecpg test\\\\a/init.pgc
michael(at)feivel:~$ grep line test\\\\a/init.c |head -1
#line 1 "test\\a/init.pgc"
michael(at)feivel:~$ gcc -o i test\\\\a/init.c -I /usr/include/postgresql/ -l ecpg
michael(at)feivel:~$

This seems to suggest that it works nicely on Linux.

So what do ou mean when saying the problem also occurs on Linux?
