* src/poptalloca.h: New file with definitions for alloca. Note: alloca is defined as malloc on systems which fail to support alloca. Don't include this file if you frequently use alloca. * src/findme.c, src/popt*.c: include poptalloca.h * src/Makefile.in: added poptalloca.h * src/menu.c (create_menu): set minimum menu width to 20 characters as it used to be (this was part of davids patches but I haven't applied it, yet).

/* 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.
