I have libz.a and can get libpng.a from some SW package (where I got 
libpng.so for links2).  What is lib*_p.a?

I was told to compile a recent version for lynx - probably by a 
perfectionist.

I think I will NOT compile statically with libc - people can add another 
libc if they want to use my package (2.1.3 to BL3).  What does glibc put 
in to make things so big?  This reminds me of Microsoft.

I have far too much added to BL2 to want to reinstall it.  I utterly 
botched it once already trying to use glibc-so.2.2.5 with the main glibc 
2.1.3 for compiling with. All sorts of things stopped working, including 
ar and the compiler.  I had to start over.  I wanted to use opera with 
2.2.5 but keep compiling with 2.1.3 so others could use the results.  I 
tried to downgrade back to 2.1.3 and could not manage that properly 
either.

I will put the png and tiff programs in a separate package for BL3 and 
warn people that they may have problems in BL2 if they already have (or 
later add) a libpng or libtiff of the same version number or earlier. I 
might suggest sticking the libc5 libraries in /usr/local/lib and pointing 
programs at them in /etc/profile.

I thought it would run just tifftopnm with /usr/local/lib libraries. So 
for tifftopnm, pnmtotiff, pngtopnm and pnmtopng I would put four such 
lines (each with a different program at the end) WHERE if not 
/etc/profile?  I don't know what EXPORT does other than choose non-default 
devices, and that is the only thing I know how to change in /etc/profile.

export GS_DEVICE=vgalib
export CDDA_DEVICE=/dev/hdc.
