Slow operation of makedepend

[Hans-Peter Budek]

Hi to all,

I tried to compile firefox on my system, but makedepend took
several hours for 'nsIconChannel.cpp'.
This delay is caused by the gdk/gtk header files which include
each other.
I made some changes in 'parse.c' to speed up the operation.
This might be useful for others, so I'm attaching the details.
