error: ‘access’ was not declared in this scope

[renato-grottesi]

Hi,

I get a trivial error when compiling in Ubuntu 20.04:

source/sdlkit.cpp: In function ‘bool ioExists(const string&)’:
source/sdlkit.cpp:182:13: error: ‘access’ was not declared in this scope
  182 |     return (access(filename.c_str(), 0) == 0);
      |             ^~~~~~

The one line fix is:

diff --git a/sfxr/source/sdlkit.cpp b/sfxr/source/sdlkit.cpp
index 2d125b0..885799c 100644
--- a/sfxr/source/sdlkit.cpp

 #include <stdio.h>

 void error (const char *file, unsigned int line, const char *msg)

After that it works fine :-)
Thanks for the great application!
