[syslinux] [PATCH 1/6] Use z width specifier when printing size_t variable
Fixes the warning: format '%x' expects argument of type 'unsigned
int', but
argument 2 has type 'size_t'

When building efi64, there's a size mismatch between the uint32_t
variable (32 bits) and the -1UL (64 bits). This fixes the warning:
large integer implicitly truncated to unsigned type

[syslinux] [PATCH 3/6] gpllib: fix sizeof(char *) misuse
The code was passing sizeof(char *) - not the length of the buffer - to
strlcpy and snprintf. Change the function to take the length of the
buffer as a parameter.
Fixes the warning: argument to 'sizeof' in 'snprintf' call is
the same
expression as the destination; did you mean to provide an explicit
length?

[syslinux] [PATCH 6/6] hdt: fix sizeof(char *) misuse
The code was passing sizeof(const char *) - not the length of the string
or the size of the buffer - as the length to strncmp(). These two cases
don't need the length, so switch to strcmp.
Fixes the warning: argument to 'sizeof' in 'strncmp' call is the
same
expression as the second source; did you mean to provide an explicit
length?
