gcc13 doesn't compile test program

CC=gcc CXX=g++ make clean test with gcc13 13.2.0_3+stdlib_flag

external/googletest/googletest/src/gtest-filepath.cc:60:25: error: 'POSIX_PATH_MAX' was not declared in this scope

Updating GoogleTest to latest commit on Jun 6, 2024 (google/googletest@a7f443b) does not resolve this issue for me.

This issue may be related some/all of the following points

• header dependencies were changed with gcc13 (https://gcc.gnu.org/gcc-13/porting_to.html)
• my gcc installation may not be able to locate the correct system header "limits.h" and may use "glimits.h" instead which does not define PATH_MAX (see discussion https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99476)

I can no longer reproduce this issue. Tested on v8.0.0 with the following compilers for make CXX=g++ clean test:

• gcc12 12.4.0_1+stdlib_flag
• gcc13 13.3.0_1+stdlib_flag
• gcc14 14.1.0_1+stdlib_flag
