3

A `gap-config` script would allow the user (and more importantly: the build systems of GAP packages) to query the CFLAGS, LDFLAGS, etc. that were used to build GAP, as well...

buildsys: should we drop libtool and simply use our own list of build rules?

9

The main reason to use libtool for us is that it provides a uniform way to generate shared libraries and loadable modules (for kernel extensions). That used to be quite...

`PROGRAM_CLEAN_UP()` (and thus exit handlers) not always run when quitting GAP

2

When GAP exits, then normally exit handlers installed via `InstallAtExit` should be run; this is done by the function `PROGRAM_CLEAN_UP()`. (The exception being when `ForceQuitGap()` is used, but that's not...

`ZmodpZObj(1, p)` is "normalized" to `Z(p)^0` if and only if `p < 256`; should it be `p < 2^16`?

Compare this: ``` gap> ZmodpZObj(1, PrevPrimeInt(256)); Z(251)^0 gap> ZmodpZObj(1, NextPrimeInt(256)); ZmodpZObj( 1, 257 ) ``` The cut-off point for `Z(p)` currently is 2^16: ``` gap> Z(PrevPrimeInt(2^16)); Z(65521) gap> Z(NextPrimeInt(2^16)); ZmodpZObj(...
