After the "hack" introduced for <https://issues.guix.gnu.org/42392>, all GCCs
are built with the current GCC's libstdc++ headers. This results in subtly
broken C++ headers in older versions, which aren't necessarily compatible with
libstdc++s from other versions.
For example, this test case works with GCC 11:
$ guix shell --container --emulate-fhs --pure -e '(@ (gnu packages gcc) gcc)' binutils -- sh -c 'echo -e "#include <cmath>\nint main() { return std::isnan(0); }" | g++ -x c++ -; echo $?'
0
but fails with GCC 9:
$ guix shell --container --emulate-fhs --pure -e '(@ (gnu packages gcc) gcc-9)' binutils -- sh -c 'echo -e "#include <cmath>\nint main() { return std::isnan(0); }" | g++ -x c++ -; echo $?'

<stdin>: In function 'int main()':

This specific error can be traced back to the GCC build, where GCC 10 and 11
are configured with:
checking for ISO C99 support in <math.h> for C++11... yes
but GCC 9 is configured with:
checking for ISO C99 support in <math.h> for C++11... no
The configure check fails due to errors like these due to the mismatched
libstdc++:
configure:17817: checking for ISO C99 support in <math.h> for C++11

Updating libstdc++ to reference each GCC works around this.

During the update of glibc from 2.35 to 2.39, the crypt.h header has
been removed from glibc's include path. Packages depending on this
header from minizip have no access to it anymore. Remove this phase.
* gnu/packages/compression.scm (minizip)[arguments]{phases}:
Delete 'remove-crypt-h phase.
