The latest gcc with the latest Cygwin complains when passing a char to
the toupper, tolower, isspace, isalnum, isprint, isdigit or isalpha
functions/macros. These functions are defined to take an integer. This
patch adds cast to int as needed to remove the warnings. After this
there are still two warnings related to a signed/unsigned comparison
in yy_get_next_buffer() (part of flex).
These are not leaks in the true sense of the word, but it is
memory that is not being freed before the program finishes
so valgrind will complain about this.
This patch adds the ability to call command files from other command
files. There is currently a limit of 16 total levels deep (15 stored
plus the current file). -f is now an alias for -c for both the command
line and command files. The parser also reports errors when they occur
along with the file name and line number to aid in debugging problems.
