mc/m4.include/vfs/mc-vfs-undelfs.m4
Andrew Borodin 0eae2cb8dc Unify m4 macro names.
Macros get from other projects keep their original names:
gl_FSTYPENAME, AX_PATH_LIB_PCRE, etc.

Macros initially writtem for MC have original names with prefix mc_:
mc_VERSION, mc_CHECK_GLIB, etc

Macros get from other projects and modified for MC keep their
original names with prefix mc_:
mc_cu_PREREQ_STAT_PROG, mc_AC_GET_FS_INFO.

dnl Set shell variable ext2fs_undel to "yes" if we have it,
dnl "no" otherwise. May define ENABLE_VFS_UNDELFS for cpp.
dnl Will set EXT2FS_UNDEL_LIBS to required libraries.
