* all: remove need for `-fcommon`Dan Cross2025-07-251-1/+1
| | | | | | | | | | Use `extern` where appropriate so that we can remove `-fcommon` on macOS and others. On macOS, `-fcommon` generates a number of linker warnings. I've tested building on macOS, Linux, FreeBSD, NetBSD, OpenBSD and illumos. I am not in a position to test on AIX or other more esoteric platforms, however.

* sam: fix spurious overwrite messageRuss Cox2021-09-301-1/+1
| | | | | | | | | | | Fixes: % sam -d -. w foo foo: (new file) #0 w foo ?warning: write might change good version of `foo'
* sam: avoid out-of-bounds read in rtermRuss Cox2021-01-141-2/+2
| | | | | | | | | | | Usually r->nused < r->nalloc and the read is in bounds. But it could in theory be right on the line and reading past the end of the allocation. Make it safe but preserve as much of the old semantics as possible. This use of rterm appears to be only for optimization purposes so the result does not matter for correctness.
* sam: remove backward ?:Russ Cox2021-01-141-1/+1
| | | | The exit code here is ignored anyway.
* acme, sam, samterm: remove weird switch usageRuss Cox2021-01-052-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | For whatever reason all three of these programs contain switches like: switch(x) { case 1: if(cond) case 2: f(); } Like Duff's device, this is legal C but more obscure than it really needs to be. This commit assumes those are intended as written and simply writes them more clearly. I did consider that maybe they are mistakes, but in the case of sam/regexp.c, my rewrite in this commit matches the acme/regx.c that has been in plan9port since I added acme in 2003. (I didn't bother to dig up the old Plan 9 releases.) Assuming acme/regx.c has been correct for the past two decades, this commit should be correct too.

| | | | | | This should make the AIX build finally work. Fixes #400.
* Trivial changes: whitespace and modes.Dan Cross2020-01-108-27/+22
| | | | | | | | | Remote whitespace at the ends of lines. Remove blank lines from the ends of files. Change modes on source files so that they are not executable. Signed-off-by: Dan Cross <cross@gajendra.net>
