Trac 17375: Maxima should not need a working C compiler to run
Trac #17375: Maxima should not need a working C compiler to run

It turns out that after the upgrade to Maxima 5.34.1 (#16908), a working
C compiler is needed to run Maxima on ECL, which is of course
inacceptable.  The problem is caused by the compilation of four regular
expressions on startup.

As a workaround until this is fixed upstream, we revert the Maxima
commit introducing this compilation.
