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 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
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.
