what does "@SOME_VALUE@" mean in C++ header -

-

i've seen in c++ headers:

#define value_a @value_a@

or

#if @value_a@ ... #endif

so, tell me @@ mean?

thanks lot.

probably got source code other source (not yours) , not someheader.h someheader.h.in

all @something@ tags substituted configure script on program configuration. configure , proper header file @something@ substituted.

some reading autoconf info documentation make light darkness.
