Hi,

For the following file test.h:

#define TEST \
1 + 2   \
3 + 4

TEST

With

pcpp test.h

I got:

1 + 23 + 4

While with

clang -E test.h

I got:

1 + 2 3 + 4

I'm not sure what the standard is, but it seems reasonable that if there are spaces before line continuation, they should be preserved?

Looks like it's been fixed in trunk for some time. I guess now we've given it a year for 1.30 to get settled, time for a release.
