Confirmed still a problem for app-text/discount-2.2.7c, but currently masked version app-text/discount-3.0.0a compiles and installs correctly.

Looks like its fixed with discount-3.0.0a
Yes unfortunately when I last checked, it breaks most consumers of discount, due to API changes. I'll take a look and see if the situation has improved. If you're just using discount directly (not as a dep of something else), feel free to unmask 3.0.0a and use it.
gcc14_tinderbox has reproduced this issue with version 2.2.7c - Updating summary.
app-text/discount-2.2.7c (as per original bug titel) is not contained to muscl, fails wtih with gcc-14 on glibc and requires use of -fpermissive main.c:311:36: warning: passing argument 2 of ‘mkd_e_code_format’ from incompatible pointer type [-Wincompatible-pointer-types] 311 | mkd_e_code_format(doc, external_codefmt); | ^~~~~~~~~~~~~~~~ | | | char * (*)(char *, int, char *)
