Is it possile to bypass the 256 bytes MAX_PATH limit? about msys2-runtime

Whatever support there is for longer paths in the MSYS2 runtime would be inherited from the Cygwin runtime. Maybe raise the issue with the kind Cygwin folks?

Thank you for your answer. I'll try to modify this value and do more test

If you increase the value, you will have to adjust your registry accordingly. See https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd for details.

(And you'll have to add that manifest entry.)

After testing for a while, I'm quite satisfy with this.
Except for adjusting registry, the only thing need to do is to change __NAME_MAX in winsup/cygwin/include/cygwin/limits.h.
If the length of given filename is beyond registry limits, the runtime will just show a File Not Found message.
I can't say this modification is safe and it may contain unknown inconsistent bugs, but at least it really helps me to solve a lot of annoying problems.

Thank you once again for your help.
