6838	Adding include file with force_include makes Wave fail to emit #line directive	Rasmus Bonnedal <rasmus.bonnedal@…>	Hartmut Kaiser	"It can be demonstrated with the wave tool:

Input files

a.cpp:
{{{
int main(void) return 0;
}}}

force.h:
{{{
int func(void);
}}}

Command line:
{{{
wave -F force.h a.cpp
}}}

Output:
{{{
#line 1 ""/Users/bonnedr/code/boost-wave-test/force.h""
int func(void);

int main(void) { return 0; }
}}}

Expected output:
{{{
#line 1 ""/Users/bonnedr/code/boost-wave-test/force.h""
int func(void);
#line 1 ""/Users/bonnedr/code/boost-wave-test/a.cpp""
int main(void) { return 0; }
}}}

I have tried a fix by changing line 756 in wave/util/cpp_iterator.hpp like this. It solves the problem for me but I don't know Boost Wave enough to know if it doesn't introduce a bunch of other problems.

Fix:
{{{
-if (iter_ctx->emitted_lines+2 == act_pos.get_line()) {
+if (iter_ctx->emitted_lines+2 == act_pos.get_line() && act_pos.get_line() != 1) {
