Hello,

I compiled curl-7.37.0 on Linux, Solaris, HP-UX, AIX and Cygwin.
It works nearly without any problems. ;)

On our old HP-UX 11.11 machine, there was a little problem in the last link step:

libtool: link: gcc -g -O0 -pedantic -Wall -W -Wpointer-arith -Wwrite-strings -Wunused -Wshadow -Winline -Wnested-externs -Wmissing-declarations -Wmissing-prototypes -Wno-
long-long -Wfloat-equal -Wno-multichar -Wsign-compare -Wundef -Wno-format-nonliteral -Wendif-labels -Wstrict-prototypes -Wdeclaration-after-statement -Wno-system-headers

I don't know, if 11.11 supports IPv6, so it seems to be a solution for me.
