package/clapack/0006-remove-uninit-f2c.patch

   1 uninit.c includes glibc-specific <fpu_control.h> not provided by musl.
   2 Somewhat portable replacement is <fenv.h>, which is available in musl
   3 but requires non-trivial changes to uninit.c.
   4
   5 f2c uses _uninit_f2c() from uninit.c to implement its -trapuv option,
   6 pre-initializiing floating-point variables to NaN and asking FPU to send
   7 SIGFPE whenever NaN value is encountered.
   8
   9 clapack source has already been run through f2c without -trapuv,
  10 so uninit.c code is not used anywhere and can be safely excluded.
