If you want just to reduce the size of the file, --excmd=number does the job: on
my system (Gentoo, so I have header files for every package that provides them)
the following command takes 1,5 minutes to generate a 265 MiB file:
ctags -R --excmd=number \
--c++-kinds=+p \
--fields=+iaS \
--extra=+q \
-f ~/tmp/vim/uitags /usr/include

I don't know how to include only standart C headers, but you may try the
following (in **zsh**):
ctags --excmd=number \
--c++-kinds=+p \
--fields=+iaS \
--extra=+q \
-f ~/tmp/vim/uitags2 \
/usr/include/*(e%'man -w $REPLY:t &>/dev/null || man -w $REPLY:t:r
&>/dev/null'%)

It will try to index only files (and directories) whose names are man entries.
With this command it generates only 29 MiB file in 50 seconds. Please don't
forget that it is zsh, not bash. And join last two lines of command, they got
splitted by mail client.
