[tlbuild] lcdf-typetools: buggy inline handling in config.h.in

[Vladimir Volovich]

Hi Eddie and Peter,

in config.h.in, there's this snippet at the end of file:

/* Get rid of a possible inline macro under C++. */
# define inline inline

(note that there's another snippet which deals with "inline" above this one).

the problem is that when config.h is generated by config.status, it does
change the above to:

/* Get rid of a possible inline macro under C++. */
# define inline __inline

when "inline" was defined to something other than "inline" or nothing (e.g.
my config.status on AIX has

D["inline"]=" __inline"

which results in the above expansion.

(apparently, config.status touches not only lines which start with #undef
but also lines with start with #define.)

this results in unwanted definition of inline as a macro when compiling
C++ files, and a build failure:
