Syslinux - Aug 2011 - fwrite?

Is there a known problem with fopen and/or fwrite in Syslinux? I'm trying 
to open a file to write data to but fopen( file_name, "w+" ) fails 
everytime. fopen( file_name, "r" ) works just fine.

Writing to files isn't supported by Syslinux.

Don Hiatt ported the ext2fs lib to Syslinux:

As far as I know, it was never merged with the official Syslinux tree.

I found his git tree:
