double underscore. Added #includes for dependent files. * popt.c: Likewise. * popthelp.c: Likewise. * tree.c: Moved a macro from tree.h to here, as it is useless outside tree.c.

/* Definitions for alloca (mostly extracted from AC_FUNC_ALLOCA). According
|
|
to the autoconf manual in dome versions of AIX the declaration of alloca
|
|
has to precede everything else execept comments and prepocessor directives,
|
|
i.e. including this file has to preceed anything else.
|
|
|
|
NOTE: alloca is redefined as malloc on systems which fail to support alloca.
|
|
Don't include this header if you frequently use alloca in order to avoid an
|
|
unlimited amount of memory leaks.
|
|
popt uses alloca only during program startup, i.e. the memory leaks caused
|
|
by this redefinition are limited.
