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