Type error in Mint/mint.cpp with last_index

[eekee]

I just cloned Freemacs today and tried to build it. I got 2 errors compiling Mint/mint.cpp. Both errors are identical:

no matching function for call to 'min(long unsigned int, long long unsigned int&)'
  227 |                 mintcount_t index = std::min(ch - 0x80UL, last_index);
      |                                     ~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~

Compile Log

last_index only appears 3 times in the source. Not knowing C++, I don't know how auto works and have no idea how to fix it.
Mint/mint.cpp:208: auto last_index = arg_vec.size() - 1;
Mint/mint.cpp:216: mintcount_t index = std::min(ch - 0x80UL, last_index);
Mint/mint.cpp:227: mintcount_t index = std::min(ch - 0x80UL, last_index);

Versions:
gcc 15.2.0-8
boost 1.89.0-1

I might be making a mistake, I'm building it the Unix way (with the Makefile) using the UCRT64 environment of MSYS2, which is meant for building Windows programs. MSYS2 lacks a boost package for its more Unix-like (Cygwin-derived) MSYS environment.

Same error under Termux, where "g++" is clang 21.1.6.

Looking at it a little more, I guess last_index needs to be dereferenced.
