Syslinux - Feb 2008 - 3.62-pre16: Compiling on old (2.4 kernel) distros

I have put a compile hack in for older distros and pushed it out as 
syslinux-3.62-pre16; for those who have reported compilation problem on 
older distros I would greatly appreciate if you could confirm if it 
works now (it worked for me on a CentOS 3.9 VM.)

Compiled fine, thanks for the fix.

One thing that seems to me like broken since several releases is the
CC variable in the toplevel Makefile. If set to gcc-3.4.6 then the
make output looks like this:

Since this point there is no more gcc-3.4.6 in the log, assuming make
is using gcc what is 4.2.3.

Using linux-2.4.36.1 vanilla kernel, gcc-3.3.1 uClibc with
make clean
make installer
It compile fine and with no warning (gcc-3.3.1) until
gcc   -o extlinux extlinux.o setadv.o extlinux_bss_bin.o extlinux_sys_bin.o
make[2]: Leaving directory `/usr/src/syslinux-3.62-pre16/extlinux'
make[2]: Entering directory `/usr/src/syslinux-3.62-pre16/sample'
pngtopnm syslogo.png | \
 ../ppmtolss16 \#000000=0 \#d0d0d0=7 \#f6f6f6=15 \
 > syslogo.lss
/bin/sh: line 1: pngtopnm: command not found

Using with nasm-0.98.39
make clean
make
there is only this warning twice
In file included from stdio.h:5,
                 from argv.c:37:
stdlib.h:7: warning: redefinition of `size_t'
/usr/lib/gcc-lib/i386-pc-linux-gnu/3.3.3/include/stddef.h:213: warning:
`size_t' previously declared here

Then it similary fail because pngtopnm is not available.


Using one sed to not depend on pngtopnm,
sed -i -e 's/all: syslogo.lss /all: /' sample/Makefile
compilation is successfull but there is some compilation warnings.
