10This patch builds on the menuconfig patch for EGLIBC.
11
12
13There are a few options that have non-boolean types, that would benefit from the new 'make *config' support:
14
15EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE (int)
16EGLIBC_NSSWITCH_FIXED_CONFIG (string)
17EGLIBC_NSSWITCH_FIXED_FUNCTIONS (string)
18
19
20The patch converts these to real options in libc/option-groups.def. Also, libc/scripts/option-groups.awk is modified to output a '#define' line for int, hex, or string options encountered in the config file.
21
22In the post-processing script config-postproc.pl, a small change is needed: for any boolean option FOO that is implicitly disabled in the kconfig output, make sure that option is indeed a boolean before printing the explicit OPTION_FOO=n.
23
24Finally, libc/malloc/Makefile passes __OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE as a CPPFLAGS, which is not necessary anymore because this macro will now be present in the generated header.
25
26attached is the updated patch to address above issues.
