This adds a warning to the top of each “boot” package that reads: Note: this package is used for bootstrapping fetchurl, and thus cannot use fetchpatch! All mutable patches (generated by GitHub or cgit) that are needed here should be included directly in Nixpkgs as files. This makes it clear to maintainer that they may need to treat this package a little differently than others. Importantly, we can’t use fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale hashes, we need to include patches that are subject to changing overtime (for instance, gitweb’s patches contain a version number at the bottom).

|
|
The GNU MPFR library is a C library for multiple-precision
|
|
floating-point computations with correct rounding. MPFR is
|
|
based on the GMP multiple-precision library.
|
|
|
|
The main goal of MPFR is to provide a library for
|
|
multiple-precision floating-point computation which is both
|
|
efficient and has a well-defined semantics. It copies the good
|
|
ideas from the ANSI/IEEE-754 standard for double-precision
|
|
floating-point arithmetic (53-bit mantissa).
