Warnings generated when compiling KPP with gcc 13 #102
Description
Report a bug or issue with KPP:
When compiling KPP on MacOSX with gcc 13, we get these warnings:
gcc -g -Wall -Wno-unused-function -I/usr/include -c code_f90.c

kpp.c:597:11: warning: passing arguments to 'Generate' without a prototype is deprecated in all versions of C and is not supported in C2x [-Wdeprecated-non-prototype]
Generate( rootFileName );
^I suspect it has to do that we are passing rootFileName to various C routines but the function prototype for these routines do not have the rootFileName argument:
code.h:190:void Use_C();
code.h:191:void Use_F();
code.h:192:void Use_F90();
code.h:193:void Use_MATLAB();
gdata.h:260:void Generate();I think this is due to stricter parsing of the source code in GCC 13.
