#74043: texlive-bin @2025.74524_1 does not rebuild on PPC Leopard, Mac OS X 10.5.8,
because TeX Live sources redefine getopt() and getenv() and in pTeX a
variable is named "bool"!

     Type:  defect       |     Status:  new
 Priority:  Normal       |  Milestone:
Component:  ports        |    Version:  2.12.5
 Keywords:  ppc leopard  |       Port:  texlive-bin
-------------------------+-------------------------
 Some dylibs were upgraded, some compilers too. MacPorts now thinks that I
 have to rebuild this port before going further, to TL '26. Builds fails.
 Now, at first install it must have worked: `texlive-bin @2025.74524_1+x11
 (active) requested_variants='' platform='darwin 9' archs='ppc'
 date='2025-04-23T13:00:29+0200'`. I did not report that re-build failure,
 hoping to solve port's problem with TL '26. But this fails as well (XeTeX
 does not build, uses too modern functions, #73853). Dvisvgm 3.6 fails to
 build either (#74035), so I asked Martin Gieseking for help. He sent me an
 eMail with the hint that hinted to a Gentoo patch. Applying it solves
 build problems with redefinitions of `getopt()` and `getenv()` on
 `Leopard`. But now I hit a problem with euptex0.c which gives a variable
 the name of built-in datatype of GCC 15, i.e. `bool`. Renaming it to
 `my_silly_bool`, or bull, would be OK, but the file is in
 `/opt/local/var/macports/build/texlive-bin-
 9d7eb26d/work/build/texk/web2c`, which is the `build` and not the `sources
 directory`. And I have no idea where this file euptex0.c  comes from…
 (leaving pTeX out from building is OK with me and a radical solution)

 The rather single-sided eMail discussion is here:
