With my latest commit ecpg uses a #define to set a different debug level and the lib sets the regression flags according to that level. This still needs a global variable in the library but it is not accessed from the outside. Hopefully this works on all archs.

It looks like Joachim's last patch thinks it's OK for libecpg to try to
reference a variable declared by the calling program. This will
surely Not Work everywhere, and even if it did work it'd be a bad idea
because it would guarantee that existing calling programs would break at
the next libecpg update. The reference has to go the other way.
Actually I'd suggest that using an exported variable at all is probably
bad style. I'd suggest that libecpg export a set() function instead:
static int ecpg_regression_mode = 0;
void ecpg_set_regression_mode(int mode) {
ecpg_regression_mode = mode;
}
