Hi Walter, Thanks for the great work.


I want to ask you to speedup the process for this ImportC issue: 
https://issues.dlang.org/show_bug.cgi?id=23926

I am use importC for a huge C header(700KB), with dmd nightly 
most of code work well.

without fix 
[#23926](https://issues.dlang.org/show_bug.cgi?id=23926), there 
is no easy way to fix this huge c code header that change 
constantly by upstream, this header is generate by amalgamation 
scripts.


There is 14K lines code, and so much function that accept 
nont-const struct pointer mixed const struct pointer.  It is not 
impractical to add so much `cast(Message*)` into D code.

Please let me know what I can do to speedup the process to fix 
this problem.

Thanks in advance.
