question: use of musl-libc

[anonymous <johnandsara2@cox.net>]

#1  a repost, kinda.  i have no idea if you all can see my post - i 
wrote a post yesterday did not appear on list

#2  i'm interested in changing out gcc and glibc in the future (so many 
are for many reasons - like build failures of unix wares, slow build 
glibc, complexity to fix its every mutating abi, non unix abi, etc)

question: should musl-libc be used to replace libc6 and or libc5-compat? 
  or no, it is "a true unix abi" but really for new embedded projects, 
current projects may need significant altering "to work" - even though 
everything says "unix ABI" on it

question: i understand what musl-libc is. very unsure how hard it would 
be to get "most linux apps" including firefox-5,20,30 to compile. 
unsure if i tried it: unsure what "prefered C compiler is" and unsure 
what intended application is.  wondering if any of you have experience 
compling (many) linux apps from source against musl-libc and what was 
easy and what (wasn't).

(? BSD went from nice fast standard C to gcc now to clang but still g++ 
?.  apple is going clang bug uses ever mutating dialect "obj c" and 
other mutating interpreters.  the whole unix maket has been attacked 
with releases of mutations that are compatible with themselves and not 
even themselves)

(i'm almost thinking euro/asia is doing anything possible to prevent any 
standards from "maturing" into more mature unix/X11 releases - because 
they are always mutating languages util they no longer work with 
anything but the relesase they are selling (android) - and even then 
cause failures - except in the products the "pgp controllers" are 
releasing for sale.  never works as they say when others try it.)
