[PATCH] libtool-1.3.5: compiling .i/.ii files

[Peter Moulder]

Libtool does not recognize .i or .ii files (which correspond to .c/.cc
files except without going through the preprocessor; see *note
(gcc):Overall Options.).

Apart from reducing compile time, they are used because on some
systems (including even FreeBSD) the output of the preprocessor can be
invalid input to the preprocessor.

I haven't checked any standards documents to see whether .i/.ii files
are universally accepted, but I have checked Irix' compiler (in addition
to GCC of course).

(Even if it turns out that .i/.ii files are not universally accepted,
applying the patch still delivers benefit to projects that are
targetted to GCC or other .i/.ii-accepting compilers.)

pjm.
