@ -970,8 +970,9 @@ REDUCING SIZE
The GNU compiler and linker have a number of options that can reduce the
size of the libcurl dynamic libraries on some platforms even further.
Specify them by providing appropriate CFLAGS and LDFLAGS variables on the
configure command-line:
CFLAGS="-ffunction-sections -fdata-sections" \
configure command-line, e.g.
CFLAGS="-Os -ffunction-sections -fdata-sections \
-fno-unwind-tables -fno-asynchronous-unwind-tables" \

Using these techniques it is possible to create a basic HTTP-only shared
libcurl library for i386 Linux platforms that is only 101 KiB in size, and
an FTP-only library that is 105 KiB in size (as of libcurl version 7.21.5,
using gcc 4.4.3).

an FTP-only library that is 108 KiB in size (as of libcurl version 7.27.0,

You may find that statically linking libcurl to your application will
result in a lower total size than dynamically linking.
