# DESCRIPTION

#   Put argv[0] into a global variable progname. On DOS-like systems,
#   modify it so that it looks nice (no full path or .exe suffix).
#
#   This .m4 file is needed allow this module to use glibc's
#   program_invocation_name.

Various changes. Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch. 2009-09-19 06:47:30 +00:00			`#`

Build: Only define HAVE_PROGRAM_INVOCATION_NAME if it is set to 1. HAVE_DECL_PROGRAM_INVOCATION_NAME is renamed to HAVE_PROGRAM_INVOCATION_NAME. Previously, HAVE_DECL_PROGRAM_INVOCATION_NAME was always set when building with autotools. CMake would only set this when it was 1, and the dos/config.h did not define it. The new macro definition is consistent across build systems. 2023-01-02 14:33:48 +00:00			`AC_CHECK_DECL([program_invocation_name], [AC_DEFINE(`
